plants are still yellowing at 1800 tds wtf!

[TREE KING]

LOL...no the sand at the bottom of your res is salts, lol....



can i ask how long you have been growing weed? how long indoors? outdoors?


i personally have been growing outdoors for over 15 years, and indoors for more than 8...and im sure theres a few ppl here that have been growing alot longer...

even i overfert sometimes....its your choice, its your plants, do as you want but in the end good or bad you will be the cause

ive probably did 30 to 40 indoor crops total in the last 7 years. joe you act like ive never looked at a res before. ive never seen white dots floating in my res and an top of that a thick sheet surrounding the entire bottom. i think thats a sign of way too much barricade. the only way to know know for sure is to find someone that has used to much of it. i even noticed this a week ago when the tds was alot lower but i didnt think anything of it so its not because the tds is this high. just to add i know for a fact i measured too much when i put it in i just didnt think it would do anything bad. i hear about some people using it as ph up thats why i wasnt worried. barricade is very concentrated stuff so it very easy to over do it. your supposed to measure 10 ml for every 100 liters. i forget how much i put but it was more than that

maybe il run a test and put a huge amount of barricade in a gallon of water and see if it creates this white sheet

If you decide to try something, my friends found that feeding their aero system with Adv Sensi Bloom that they had to start at about 200 ppm on the clones and at bloom lights used BB for a week before change or so and slowly moved up to max at 1200 until Clearex rinse and then plain water flush. They set pH at 5.8 and didn't mess with it until it hit 5.3. They let the ppms float do the same thing instead of screwing with the res every day. Seemed to get into a cycle and liked it. Their product competed well with top shelf/grade dispensary stuff and customers ate it up.
They were using low ppm RO and added a very light Cal/Mag does on occasion. It makes me think that most people are using way too much nutes and stuff and they need to make a bare minimum run to establish what ppm a particular system works best at. Sure it costs time and money but after the loss they should have gain from then on...but who the hell am I to say anything....

OH yeah, forgot to mention that the ph sweep from 5.8 to 5.3 avoided lockout and allowed different nute to be taken in at the appropriate pH number...and remember, this was not F&D but aero hydro...for those following this thread...waiting for pics !

you wont find anyone using barricade, it was taken off the shelves years ago...


and even if this was the case that you put too much barricade, flushing is still your only option. by adding other stuff to amend it you will just worsen your plants

tell you the truth thats exactly what i usually do. for my moms ive never had to raise my nutes above 1200. the only difference between me and your friends is my ph rises not falls. i start at 5.6 and let it drift to 6.0.

i respect your opinion joe so well have to see what happens. il keep on giving updates until the problem is resolved. if the yellowing goes away tonight at this much lower tds than that would be a good sign

 

[TREE KING]

just flush with ph'd water then mix up a legit mix bro


it could be the potassium silicate but just removing that from the mix won't balance out the enviro of the cubes especially not watering once a day.


humble up and look what people are saying post your full mix and some pics

sorry but i cant find my camera. my full recipe is sensi 2 part, big bud, and bud candy. and im foliar feeding scorpion juice

 

[TREE KING]

just wanted to update you guys. plants are greening up again and growing more vigorous than anytime before. i now realize i made the right decision not flushing with plain water. the way it looks now the only problem il have is knowing how many times per day to flood the tray. i just cant wait to see if the plants are gonna be yellowish again when the lights turn on tomorrow. il give you guys an update tomorrow when the lights turn on thanks once again. guys i got a question for you all on a different subject if you dont mind.

do you guys recommend using veg nutes the first 2 weeks of flower? i planned on doing that this crop too but i realized i made a mistake and put bloom nutes in by accident. i need my plants to stretch the most amount possible the first 2 weeks because i dont do veg time

glad your getting a handle on it I use to do flood and drain at 4 times a day for 15 mins they were pretty happy . Good luck

tell you the truth even after i changed the res the plants were still yellow the next day when the lights cam on. now im thinking i might not be watering enough. i lowered the tds to 800 and stepped up the watering to 4 time during lights on and once in the middle of the dark cycle. theres a chance it might be because im using these pargro quick drain cubes and they need to be flooded constantly. this never happened to me when i was using the grodan cubes. if the plants are yellowish when the lights come on tonight im gonna step up the watering more to every 3 hours. im not outta the woods yet lets see what happens

Do the roots look happy?

Flush 1 plant with 1.0 EC/5.8 PH nutes. Catch the first pint of run off and test it. I bet it will tell you your problem, and it should only take 5 minutes. Guessing it might be this or that, is getting you nowhere.

im doing it now. i just took some pics too but my camera is unable to connect to my mac running snow leopard. i tried to instal the software from the cd but it spits it out. its probably cause i bought the camera 4-5 years ago. i got a kodak easyshare c433 so i gotta figure this out

 

[TREE KING]

wow so this is what checking the run off is huh guys. i think we might have something. after flooding the tray an hour and a half ago i just squeezed a little water from a cube and the ph was 6.3. is it the higher the ph the less mag the plant can take in? roots look fine to me

what do i do, start keeping my res at 4.9 to balance it out?

fuck no!! ph below 5.5 starts to fuck up rockwool, starts changing composition..

your PH at 6.3 is not a big deal....

water at 5.6 and it should balance out to 5.8-5.9....

check runoff in a few days and see whats up.....

i havent read the whole thread, just answering the last question....

but ive been watering at 5.6 since day 1 for 15 days? if that was gonna work it probably should of happened by now. to correct that mostly 5.6 the highest it drifted was 5.8. since i was topping off alot and dumping in more nutes constantly i was doing 5.6 more often. is changing the composition really that serious krunchbubble? i just want this shit to be fixed asap and i only got 6 weeks left on using the cubes

hmmm, again, i didnt read the whole thread....

im taking clones, right after i will read the whole thread and see if i can help you out, usually can....

[SacredBreh]

Agree......

Agree......

Agree with Krunch..... that to me is a good pH swing. Start at 5.5 and swing up 6.3 give a good point in the pH for each nutrient to be optimally able to uptake each nute. Only thing might concern me is if over night without floods if the pH is rising way to high without flushes to bring it down. Rockwool is not my thing though.

Peace

were talkin about the runoff being at 6.3 not the swing. i never have a problem with the swing, i do 5.6-6.0

krunchbubble after thinking about this for a moment i realize this has nothing to do with how often i flood. i just felt the cubes and they got crazy water in them and have never been near bone dry from day 1. i was just trying different things cause thats the only other thing i could think of that could be wrong. im starting to think its the run off

 

[krunchbubble]

wow, there is alot of different info in this thread....

silica lockout WILL cause yellowing that looks like nitrogen deficiency...
i used to get it alot, going by the directions....
i finally use 1/4 strength and the lockout stopped....

i dont think your ppm is to high, i flood with 1600+ ppm's, even with seedlings and they are perfect.....

the amount of times to flood, im still figuring out since i just tarted flood and drain a few months ago...
i ended up with 4 times a day for 2 minutes...
but i ALSO use a coco mat under my 4" cubes, keeps the roots moist...

best i could help .....ill keep an eye on this thread....
