(Dark) green leaves at harvest time?! Come on guys, stop overfeeding & flush fully

P

perakko

ok, thanks for the quick reply.

let's see the strain on that picture is female seeds grapefruit i did let her go a few days more after the photo. took here down at about 10,5 weeks.

i dont have anything written down but in this case she was fed with biobizz bio bloom from about 2 weeks into flowering, once a week started with about 3ml/1,5l of water (grown in 10l containers) gradually upping the dose about, 0,5-1 ml/week, fed so until 8 weeks, and after that flushing with straight water.

for nitrogen i use just basic market fertilizer, called substral (npk 6-1-5) as needed, up until like 4th week of 12/12 depending on a strain.

the first pic is of a white russian cut that i'm currently running for the second time, shes facing a few more weeks of flushing so i'll let you see how she looks at harvest time.

Hi perakko,

Thanks for the feeding info - of course, it's just an example, as every plant has different requirements.

Regarding the WR clone - you're on the 2nd run, and still need to get her more dialled in I think, but based on your skills and experience, I don't think that will be too much of a problem if you pay careful attention to her needs.

Maybe making written notes could help you achieve perfection with her? I know keeping a feeding diary has helped me in the past, especially when I've been running a lot of new plants.

I look forward to seeing what you do with her this run, and am sure that before too long, with some close attention to her, you'll have her really dialled in.

yea, i think it would be good idea to start writing down things. i think i'll start in the fall as thats when i'm starting my next perpetual grow with some long flowering sativas and i think it's gonna be a handfull...

the thing is that i'm not THAT experienced grower but i love variety and wouldn't even consider running just a few strains. right now i have 7 plants going, all different strains so it's hard to pull my best effort on all of them. also haven't yet found those keepers that would keep me interested for more than a few rounds.

anyway, thanks for your input BB and let's keep this thread going.

Hi perakko,

Ok cool & you're not that experienced maybe, but I can see you have a greenfinger, know what you're doing and all you need is a little guidance in the right direction to get everything totally dialled in and running as smoothly as possible.

I appreciate to someone with little experience, 7 plants may be a bit hard to keep track of, and we've all been there, but personally I've been up to circa.150 different female plants growing at the same time - maybe you can see why it helped me to keep notes with those, lol

Regarding long flowering sativa-doms (full blown sativas are barely manageable indoors, and not worth the effort imo), you will find that they generally want more food and a lot more light than indicas. They can be finicky with their feed too, so pay close attention!

Whatever

I grow in soil and use organic ferts (liquid) but still flush for the last week or 2 ... Altho I've read a lot saying u don't need to flush with organics (I figure its jst guna save me fert, which saves me money lol)

Dr. Greenfinger...true organics gives you much more leeway regarding any 'flush'. The dude that's teaching me has been growing and breeding for 30 years, writes for a major weed magazine on a regular basis, has a few books in the works with the publisher ready to go and promote em, etc. During my first organic grow I added a top dressing late cause I didn't add enough in the beginning and most were very green when plucked. I asked him and he showed some pics of a green plant he harvested and the ash also and it was white. He said don't worry when running organics and he was right. Sure I'll get my nute timing down a little better but the weed so far has been awesome...better than any hydro I've had with a 'proper' flush. The fragrances and flavors (especially) are off the charts and the smoke is smooooth.

I mean organic tomato gardeners don't flush their plants and they're fantastic...lol.

However I do not use liquid ferts except sometimes in veg. I use layers, spikes and top dressing of dry nutes and some teas. Are the liquid ferts you're using 100% organic or is it something like Pure Blend Pro?

these girls finished just the way I like them.

I think B.C. made one of the most interesting comments regarding uptake.

I am an ammended pro-mix grower (sometimes non-amended) and there is a point around 3/4 of the way in where they really slow down on the water.

peace

I see like this, I think my plants look good, they smoke great and have a proper flush every time. I've had strains that flush out like British says with the colors and all and I have ones that look like they are just drained of nitrogen. I know what my skill level is and I take no offence to his judgement. As long as I'm happy with what I do and can get others involved in the hobby I love so much by postin my grows I'll be a happy man and if he smoked my finished product I promise he would also be happy with my grow's. :headbange so fuck it lets just grow


Straight up, Zoo. If it smokes good, smells good, tastes good, who the fuck cares if the leaves are super yellow? Different strains do different things anyway...and this I've found over nearly 20 years of hydro growing. Don't let anyone tell you otherwise :rant:

I agree as I have noticed the same thing from the dozens of different strains I have grown in the past. That said, I can understand where BB is coming from. Some just don't flush enough. I think if your growing organic then you don't need the flush, at least as much as the chem ferts do.

I learned the way is as British_Bulldog says through my earlier research some years ago. Except for the tips, I was taught to get the plant on the edge of burning. I've never had burnt tips until my crop growing at the moment. I believe this was from all the spraying I had done to rid my first ever mite problem in 6 years of growing in doors & every plant has this now. I feed all different levels so it doesn't seem possible it's anything but spraying. I have burnt my plants though it just never seems to leave the very ends of the tips burnt as the ones in my grow. It usually just torched a leaf here & there showing burnt rust spots with some twisting or complete twist & burn. But not the customary browning of the tips.

Than I'm with if it works for the gardener than do it your way. It's funny how new things really shake some people up around here. Like my no pH grow in PM LoL you'd think it was a new idea or something, nope tried & tested just not by U or you.

Whatever - Finally someone with some input to my questions! haha. Thanks.
The liquid ferts I'm using are supposedly 100% organic, but my 2 week flush would take care of any parts of chem fert in there anyway.
I always grow organic now, after tasting weed grown in all sorts of ways, the best is always organic. That's just my opinion tho.

I have noticed my grows getting better and better with each run I do, I like to experiment a little bit too, has helped me out here and there.

So is there anyway to achieve this 'award winning' autumn colour with organics or is there just no point to it?

Cheers.

This is aimed at most of the growers on this site, so that probably includes you!




she yellowed some before chop 10 days after pic was taken strain is a hybrid cross urkel x strawberry desiel {strawberry desiel pheno} @ 43 days hey Sirsmokealot dose this byotch taste bad :muahaha:
lets find better pics




Decapation another hybrid cross Bubba pre98 x whitemustang {chemdog xwest coast dog bx3} also @ 43 days he also yellowed up some hey Sir hows this babie taste



memoryloss fast veggn urkel pheno better ??? oh yes where i live july average above 110 degrees outside sometime above 115 untill aug.


sugar shack 48 days flower choped wk l8r






grape krush not everything i grow turns nice picture perfect autum colors




approx wk before harvest eh 10 different strains growing in this direct above pic
lighting
400w hps
400w mh
nutes i water 1st time with plain PH water then ferts for next watering i alternate this cycle untill flush 10 days before chop.
soil fox farm ocean forrest right outta the bag
liquid karma
diamond necture
sweet
seaweed extract
pure blend pro grow
during veg i start at 10 ml everything above per gal water then i PH @ 6.5 i run everything above until 18-21 days flower i drop the pure blend pro grow seaweed extract. and add
pure blend pro bloom
indoneasion dry guano
i introduce guano 3 wks in flower 1 tsp per gal soil top dressing every other watering. at 30 days flower i hit them every watering with guano but still alternate the fert feedings. 10 days before chop i use plain PH'd water @ 6.5 i still use guano untill 5 days before chop. all plants weather it be fresh rooted clone or seedling with 2nd set of 3 finger leaves otu they all start on 10ml each of every fert listed above per gal water. i bring them upto 20ml and hold them there untill pre harvest flush begins. wow now after this read and my reply i need to kick back enjoy the sun on the island and burn a huge dutch tulip










my sugar shack dose like to yellow some but your opening statements are absurd

arghhhhhh lol just before i chop i cut a large fan leaf off and chew the stem if it tastes like water ready for salad. then that Biotch gets the fn ax plain and simple but if she's bitter in any way she gets watered again like norm until the stem isnt bitter tasting. my plants work into after 1wk in a new container every other day water schudel untill chop

I disagree with this a little...

Firstly, if you experience yellowing of your leafs that means the plant has a deficiency. What happens when you have a deficency? The plants metabolism slows down and therefore produces less flowers and thc...the stuff we want.

Compare to a human body... malnutrition leads to your body having to take something from another place or find alternatives to replace whatever you are missing. Therefore it is working extra instead of running 100%.

In the case of our loved marijuana plant, we want it to produce maxium thc and yield. I would suggest dialing in a feeding schedule that will allow your plant to remain efficent until it is ripe for the picking.

I guess my whole point is that if your leaves are green throughout flushing until harvest, you have done a good job. If they are too dark then that probably means you fed too much Nitrogen and should continue to flush longer. If they are yellow and dying you didn't screw up per say, but the plant could have performed better had it not had a deficiency.

Either way keep growing.

If you want to shoot for a plaque on the wall or trophy in the case go for it...lol. It's really not necessary though with true organics. I don't bottle feed like you. I use dry amendments in layers, pockets, zones and top dressings. It's very hard to overfeed this way. It's also virtually impossible to flush cause you have concentrated areas of nutes that really won't wash through the soil. If your nute additions are out of balance, like too much blood meal that's not buffered properly, you're gonna run into problems. After awhile you start to get it dialed in and the plants are healthier and start to finish up a bit better where it starts to eat itself up. While this is the ultimate goal it is just not necessary. Global feeding the way you do can lead to problems.

I rely totally on the soil microherd to do all the work for me and don't put any salts in the soil. Something like PBP is not 100% organic by my definition. Go over to the Organic Soil here at IC. There's some excellent organic growers that hang there and some great threads.

I've run GH hydro, AN hydro, AN soilless, PBP soilless and now true living organics in soil. I've played with flushing, the point about plants taking up less water right at the end is a good one, in all those cases and like my buddy said...just not necessary with true organics in soil.

Maj.PotHead are you trying to communicate with moi? If yes, it's nice of you to offer me that bud to taste. PM me & I'll get you a PO Box#. Photos can be very misleading. From the thumbnails they look tasty.

I'm in straight Pro-Mix & we leach with a 10-25% PBP Bloom type nutrient in the last couple weeks they get that every watering. Only the last couple waterings will be plain no pH'd tap water. I've stopped all N except what's in the PBP after 2-3 week of bloom.

not got many end result pics, dont like to take shots when they look so "worn out"

im open to critisism

bio bizz nutes 1/2 feed all the way through, 10 day flush


another hashberry , same nutes and extra few days of water



autum colours - jackie p - water for last 4 wks


orange diesel autum colours ,but not completely flushed at time of pic










as u can see some are flushed better than others ,but 2 wks of water should be plenty, if nutes arent dosed high throughout grow

:joint:

there seems to have been a problem in the system, a lot of other peoples posts from today are missing too, so it's not just you. i'm sure it'll be solved soon...

Well a long post of mine, as well as some shorter posts, have gone missing too - hopefully they will reappear soon :-/

m@rg, your plants don't look 'worn out' to me, they're looking fairly good, and well done on the good feeding and flushing regime :yes:

One of my posts was actually referring to the aspect yours are showing, with the colourful autumn leaves, and this was the result of lower night temps.

The 2nd pic looks too early/immature for autumn, but the others look quite good.

I would say that you can get them to use up more of that remaining food next time though ;)

Re-look at Ty-Stik's pic, and that's what you should be aiming for.

Whatever, I don't mean ta be critical and I"m not tryin to offend you but you need ta read some more on how ta use amendments. When you use them, you mix em up -very- well in the soil, make a bioactive tea ta wet the soil with and let it sit and cook for at -least- 2-3 weeks. By makin layers, pockets, and zones yer gonna cause imbalances. The roots hit these concentrated spots and over do it in that certain nutrient, causing a lockout of other nutes, not ta mention the ph in these spot are gonna be off. Also, having concentrated nutes in one layer or spot in yer soil just about guarantee's yer not gonna use it all before yer plants are done. Useing soil like Fox farm and feeding the microherd well till the end will play that soil out and yul have no issues with nasty tasting bud. Esp giving em jus plain water the last week of the transpiration cycle ( yellow leaves ). Working with soil really has it's benifits, the soil food web takes care of yer plants in many ways. Like braking down the waste/salts that a plant exudes through it's roots. It will also brake down the salts in the soil from nutes themselves allowing them ta be flushed away if need be..... Sorry, I could ramble on ferever when I'm stoned. lol I'll stop here tho. later BC
