Supercrop time! 
Nice job. I am all for CMH too.

They do look fairly well from far back, lots of places for nuggies
@The Vermonster
Running a 400W SOG as well? wouldn't mind seeing your pics
@Kenny Lingus
Dont hold back, i may have grown before but my worst harvest was 9 ounces off 800 watts, so i've got plenty of room to improve. I've never even cracked .5G/watt, but i'm hoping now that i'm not growing in an 18" wide closet that will help. In terms of the EC though, i read through a thread called Neptune's Breakdown. Neptune ran these hindu skunks with a 3 week veg under 600's, and fed them EC1.0-1.1 the whole time. My ladies just got bumped back to 1.0 from 0.85, and i think they might be getting more crispy again, going to have to keep EC low.
@Wickkk
I can definatly suggest the coco drip setups. At least to me this seems like the easiest way i could grow pot, soil hydro or otherwise.

Hi Hurricane!
-0,8-1,2 gpw is very achievable in coir on drip or hand fed...
The most important thing in coco as I see it is to keep the medium on the wetter side (multiple feedings until some drip out below) or if feeding once a day to give enough for 5-20% run-off. (On the other hand: you can also grow more conventionally like in soil where you take advantage of dry/wet cycles to improve aeration, but then I find it's best to give water-nutes every other time I need to soak the pots, or just a weekly 7-day cycle like this: nutes day 1 -nutes day 3 -water w/flushing day 5
If you do not ensure enough leaching of unused/exuded salts most coco grows experience problems in mid/late bloom. (loads of enzyme, bacteria, and humic acids may offset this phenomenon, but for most indoor weed growers I think the proven way of feeding and choice of nutrients will be best.
PS! -My best results in coco so you have the far are with auto drip 3-5times daily in slabs until a little run off occur, and hand fertilization daily with 10% runoff in 3-8 liter pots of canna coco.
It could be that the best choice would be more air movement and get moist-hot air vented outside... (your relatively low temps may make it wiser to salvage the heat somehow, so I really dunno.) Proper venting is VERY crucial when aiming for the fine yields that make this all so rewarding. (You don't need plenty of rotten buds if you even get them plumped in a stagnant sauna)
-Rain-ex may help some with the foggy glass, but will allow the condense to form droplets running straight down to the sill and pool up there. Keep a towel or good long term kitty litter/water polymer crystals/etc. similar to suck it up. Maybe spread some chalk/lime to avvoid molds... Dehumidifier boxes with chemicals that trap the water in a box may also help, at least if you seal off most off the window and let it rest in the enclosed area.

Greetings Again Everyone, by request from Wickkk we have a new round of pictures :smile: Its flower day 24 and as we can see in the pics stretch is mostly over and bud production is getting into full swing. Hopefully by day 35 there will be some nice nuggies. One of my fav parts of the grow is when the plants are a few weeks from harvest, because i rub the inside of a few rolling papers against the fresh nugs. With some good herb those sticky papers are great 
Plants are doing well enough, although i didn't drop the ec enough, or for long enough from my previous round of overfert and its still continuing. A cpl days ago i flushed the plants with 24G of water, and am now feeding them at EC0.6. I know thats incredibly low for flowering, but they are burning and crisping up, it has to be done.
@Kenny Lingus
This grow is seeming more and more like a test grow than a return to growing, all my variables are changing as i got through the grow, trying to decide how to run the system. I'm thinking from this point on i'm just going to set the watering timer on daily(adjusting each week for every other day is getting tedious, and i will prob just screw it up).
In relation to the humidity, its been arround 45% daytime. I'm going to have to check in a couple days for their "nighttime" humidity, as its been raining all day i've been reading high 50's in the closet, but i think its normally lower. I'm thinking about options to get the air out the bedroom, although then i worry about the temps dropping alot. i already can barely maintain 70-75 degrees daytime with the window cracked a few inches and the fan on low. Unfortunatly moving my hut might be the best solution, as right now its near the window and 2 of the 3 intakes get mostly cold outdoor air. If i were to move it opposite the room the air would be better mixed. Its worth noting that with the ventilation setup as is, the air in that room generally smells fresher than my front room(which to be fair i smoke cig's in half the day), and never seems humid. Might have to move one of my sensors out into the room itself to get an idea on humidity change.
Also throwing in a few pictures of my clone setup. The plan with these clones here is to make 2 Bonsai Mom's out of each genetic i have. I copied Lou's guaranteed 7 day cloner. Right now the WRxWW clones are on day 10 and the first one started showing roots. The HS Clones are on Day 8 and showing nothing yet. In there there are 4 clones cut off the mom you see, its a WRxWW seed plant from Holland(my friend thinks nirvana, he bought the seeds years ago on a trip). The other lighter green clones you see are lower branches i trimmed from the Hindu Skunks that I'm hoping will clone and save these genetics. Unfortunately they are looking like they will be much too slow for me to turn them into moms, so i will have to clone out the WRxWW when the time comes and that will be my genetics for the next round. This WRxWW has never been flowered, except to check for femininity, so no clue what to expect. I think they are from nirvana if anyone has grown that seed strain I'd love to hear about it.

edit: Re-Worked the exhaust a little bit with an additional 25' of flexible insulated 6" tube. Now the exhaust goes straight out the window. In the last 24hrs my min/max shows 68-76 degrees, 45-61% humidity. Reset it and will see if its any different tomorrow. Partially affecting this is the rain outside, but it seems similar to what I've seen other sunny days. Mildly disapointed that the extra tubing didn't dampen the fan noise any more, but to be fair the stanley on low is quiet as fans go. Standing 4' from the hut i can hear the circulation water pump making its waterfall noise, being that the water level is getting low and the pumps output is roughly 1/4" above the waterline.
re-edit: hmm, aparently if i upload photos of the same name they overwrite eachother, had to re-upload and fix a few photo links.

hurricane,
First I want to congratulate you on such a fine job at documenting this grow. I love the detail. Did you ever buy that battery for the timer?
Underfert can look just like overfert. .8 - 1.0 EC is nothing at this stage of growth. I'll root clones @ .8
Those crispy tips are definitely NOT from overfert. Use common sense, overfert would be impossible @ 1.0 EC.
My opinion based on growing with coco for several years is that the tip burn you are seeing is from salts left behind in the coco. Your method of rinsing the coco was inadequate. It should of been soaked and squeezed out with warm water a few times rather than simply dripping through (and a recirculated drip at that)! At this point just go forward and ignore the damage. Bring the nutes up to normal ( 1.6 - 1.7 EC at this stage ), dose your PK and get on with it.

Back here for day 27 with another update. Same as before, just finishing off the res i mixed up at ec 0.6 today. It does seem the lower feeds have stalled them. They seem a bit larger in person, but i find it difficult to discern significant differences between my day 27 and 23 pictures. The next res will be mixed at 1.0, neptune ran these hindu skunks in coco at a mix of about ec1.1(10ml pbpb+3ml calmag) to the end with very nice results, so i havn't planned to push past that.
Also in the clone room, all 4 of the WRxWW cuts put down roots, with that first one putting of quite a few by now. Also one of my Hindu Skunk cuts(which were made 2 or 3 days after the WRxWW cuts) has a single root poking out, so hopefully those cuts will all root as well.
@BlindDate
Thanks for stopping by, always good to get a little more advice. I actually did pickup batteries for the timer, surprised even myself. The thing that makes me think this is overfert is that i fed them a couple times at ec1.8 while they were just finnaly getting settled into their pots not realizing how much it was. They started showing signs of overfert a little later, i backed off the nutes for a cpl days, then went back on em at 1.0. Soon as i went back to 1.0 they continued as before, so i figured a good flush and some weak feeds would be in order. I probably shouldn't have given them a whole week of weak feeds though.
In relation to flushing, my clones are just about ready to go into their little pots. I still have a large brick that should make >50L of coco. The plan is to break a chunk off it. Rehydrate that in pure RO water. After that i will soak to coco with warm water, squeeze out, and repeat 3 times. After that i would seperate it into the pots, and hand-feed ro water through till the EC was at 0.1 or lower(might already be there from the warm wash/squeeze?). Finally hand-water through some pbpg and calmag @ec0.7to put some basic nutes in the coco.
Few questions about the warm water though, or more I suppose the opinions on flushing with tap water. My regular tap comes out at EC0.6. If i use warm tap water to flush them, I'm putting in as much as I'm taking out. I could mix the hottest tap that comes out with some RO to get the temperature to warm, probably have an EC of 0.2 or so. Could also just heat RO water on the stove to get it warm enough to flush. Heating enough RO to wash a gallon or two for moms wont be hard. I'm thinking more about how much water i would have to heat to flush the 32G of coco in the hut when i do next round.
Anyways heres the pics for today, Flowering Day 27

Hurricane, I remember that when you were setting up your grow, I had mentioned to you know about the hydrohut problem. You didn't seem too concerned about it and kinda blew me off, but I would start paying attention to it now if I were you.
It took a while for my problems to kick in (higher heat), but if everything else is perfect, pay attention to the hut. My problems started very similar.
Good luck on your grow, bud. I hope I'm wrong. You seem to have all your other ducks aligned nicely.

Lo
@HenDokuYaku
I will keep a watch for it, but my original research showed people complaining about immediate problems with the hydro hut, with the leaves yellowing out from the center on new growth. My new growth is perfect, its only the older middle leaves that are yellowing from the tips in. Besides I've never grown a pot plant green from beginning to end, they always get brown or yellow leaves. In fact I've only had a grand total of 1 leaf fall off so far this run so cant be doing too bad, I've done much worse in a "non-poisonous" C24 cab.

Mine took about 3 weeks before it started causing problems. I never had leaves fall off during the issues. Either way, I understand you got it under control. Good luck on your grow.
The nice thing about these predictions is bad hydrohuts kill plants(or at least, thats what was everyone was screaming about in the Hydrohut sick plants thread, dont tell me now its just mildly bad and makes your plants grow slower), so we will have an answer even if we disagree, based on harvest
To be honest since i already owned the hydrohut tent when i found out about issues, the ammount of ranting and raving(comparable to a good 16th century church session) going on in the hydro hut sick plants thread made me want to see if my hut was good or bad even more. If theres one thing you can tell from my thread is i like having lots of data. The main use for this thread is so i have a log of how these hindu skunks grew when i run them through again with the moms i'm making, and to read everyones advice again at the begining of the grow, so i can make a better plan.
About the hut, when i put a couple generic ferns from home depot in there for two weeks they grew happily. Since then i've had my plants in there more than a month and they've grown at least as well as any other grow i've done. The final answer will be in the harvest, or lack there of if this hut(or every hut made by HH after a certain time period, according to the thread) manages to kill all my plants. I'm not here to find out if all huts are bad, and tbh thats not my problem. I'm just trying to find out if my hut is bad. And i'm not adverse to admitting its the hut, its just that the description was specifically about yellowing from the center out, and any lightening i'm seeing is coming from the edges and doesn't look any different that how i've seen leaves break down in my previous grows(which all involved the same gallon jug i'm still using of PBPSB)
I'm sure if everything was perfect i would worry about the hut, luckily there is a human being running the show so i know nothings perfect One such example is 3 days ago i bought 1/2L bottles of 4.01 and 7.01 pH solution. When I recalibrated my ph pen it read the 7.01 solution as 7.7, so keep that in mind with all my previous pH readings
edit: @BlindDate
Thanks for looking at the pics, did you by chance read the wall of text i wrote you about flushing? Still like to have the good lowdown on it before i prepare the coco for my rooted clones(cpl days).
Enough talk i gotta get back to smoking. Bought a new pipe today which is mostly fumed(i think thats the word). Very little color shows when the pipe is clean, but i have another from the same blower and they color up very nicely when dirty. Got to work harder on making this one dirty to find out
Mixed the new res:
12G RO water -> 7ppm + 5G tap water -> 100ppm + 35ml CalMag+ ->180 ppm + approx 140ml pbpsb -> 487ppm -> 1.0EC@0.5. pH down'd to 6.0

It sounds like you have a pre-problem hut. Congratutlations.

Hey how are you finding your 400w cmh?
I am having mixed results... my recent batch of Reclining Buddahs didnt have their usual dense nugs... plants love the CMH when producing lots of white pistils but didnt produce as much trichs... They look super healthy when growing but yeah buds shrink a bit when dried...
reckon i will switch back to hps in a day or two to finish off my batch now into week 5 of flower.
Good luck with yours.

some added info for you guys

Hurricane nice looking plants very healthy looking.
silversurfer, i have a 400w cmh and my friend has a 600w hps. We have grown the same plant from clone, started within a few days of each other. And i noticed that his plants produced larger fuller looking nugs. On the other hand I was able to get more crystals and a stronger odor with alot less heat and stretch from the cmh. Now this wasn't done as a true test but turned into a fairly informal test. We used flora nova with some liquid karma in a soiless mix of perlite coco and moss mix. Growing small/medium sized plants about 1-1.5 oz a plant in small closet setup. The two biggest differences: 1.the high from the cmh was cleaner and stronger, compared to the hps. 2. The HPS produced a little bit more but only about 1/4-1/2 oz in weight per plant even though it looked like more for the HPS. The CMH buds are heavier then the same sized hps buds when put in equal sized jars and weighed. We have some room to improve on our total production but that comes with time/ experience. My new setup is pure coco And my results so far have doubled from my soil less / mix, so i will see how it likes the cmh. I hope this gives you a bit more info to work with or compare too. I wish it was 400cmh Vs 400hps but I can't be perfect.

green tea...........a 400 watter is perfect for a 3x3 area........i used to use hydrohuts both were 3x3 and both had 400's in em.......heat was not an issue at all because i had a stanley blower exhausting the hot air out..........
Back for a final update, sorry its been so long my camera died and i've sorta lost interest in documenting here w/out pictures. The plants did harvest, although a week early due to some other issues. Total yield was about 6 ounces so definatly nothing amazing. The quality of the smoke is excelent though, completely covered in trich's with a strong smell.
Current run i have 5 of the Hindu Skunks again and 2 White WidowxWhite Rhino plants at week 5. This time I'm using the Canna Coco A&B w/ Rhizotonic, Cannazym and pk13/14(just finished the pk 13/14 week and reset the res 2 days ago.) Plants are looking much fuller this time, although i'm not sure if i can put that to the nutes, or that I'm running less plants with arround 2 weeks of veg this time(flowered at about 14-15 inches).
I'm getting some of the same odd bleaching, even though the nutrients are completely different. I'm now willing to atribute this to the hut, and have ordered a homebox L. It seems i was running enough ventilation to prevent any serious issues, but the hut is likely still emiting some sort of poison affecting my plants.
edit:
in relation to the size/my happiness with a growing hut of some sort, its through the roof. I made my own C22 cab setup before and it is measurably more work than these huts. The hydrohut may have been a bad item, but the concept is good and several other companies are running with excellent products(notably the Homebox, and Secret Jardin). I especially love the large sizes secret jardin has available, large enough for a "room within a room" sporting 4k watts of light, although with me growing for personal use at 400W i'll never need one
In terms of how much light in the huts that are just over 3x3(dont get 3x3 exactly, wont fit most 3x3 tray/res combos) a 400W is excellent. I often think i could get away with 600W, but not in the summer. I'm also using a stanley blower for ventilation.
