4 weeks flowing. yellowing droopy leaves

yellowing droopy leaves with brown crispy spots randomly on it. many tips of the leaves are crispy and brown, but this may be from heat. not sure. the leaves on the bottom of the plant are yellowing and drooping. some are mushy to the touch.

the brown spots are sometimes across random areas of the leave making it super brittle and cracks to dust.

ph has been around 6.2-6.8 in a hydro setup. using hydrogaurd and florashield with gen hydro nuts mixed at 2/3 strength for bloom.

the plant almost stopped growing completely after i changed the nutriuents last.

i have drained half of the buckets water and replaced it with pure distilled water to lower the nutrient content as i originally thought it was nutrient burn starting. after reading more its now looking closer to a phosporus defeciancy.

can low amounts of nutrients do this much damage this fast? i figured only going overboard with nuts could do this in a week or so.this is my first female ever after 2 years of trying. save her. thanks.

here is some pics.

I think 6.2 - 6.8 ph is too high for a hydro setup

well, i try and keep it lower, but i was being realistic. its always a little more base in the morning than it was when i went to bed.

i dont have a electric meter and i use gen hydro brand ph liquid. is it pretty accurate? its all i have ever had to use. i try and keep the color orangish yellow.

but i dont think thats the issue. i have checked ph 20X over. its right on the money right now, and the same range as it has been growing in for 2 months or so.

since i am not sure what the problem is and something had to be done, i simply changed the water and nutrients and used a simple 2 part bloom for now.

do u have a ppm meter
whaats the ppm now
i think its a P def but not positive

i dont have a ppm meter. i have been reading gen hydro nuts need to be mixed at 50% the strength reccomended on the bottle? is this true? i have been mixing at 2/3 stregth of bloom phase mix on the bottle, and now this suddenly.

anyone else have some advice or diagnosis? i clipped off 2 handfuls of yellow, droopy, and ugly fan leaves.

the leaves on the cola arms dont appear to be as effected....yet.... its been about a week since she stopped growing.

i have her in a very aggressive training SOG, so i cannot lift the lid to look at her roots. i am assuming they are good as they have always been since i switched to 5 gallon buckets. she has tons of air. 2 simple air stones powered by 2 twin outlet wal-mart pumps. no light hitting roots and the temps on the SOG screen are between 82-86 on average. the ambient temps are in the high 70's or low 80's.

these cfls are really putting off some heat. i have about 360 (actual) watts of cfls in a 6 foot tall, 3.5 feet wide by 2 feet deep.

sorry for getting off subject, just trying to give as much info as you guys need to make a better judgment.

if you would like more pics or plants or setup or macro pics, let me know.

wow, i just noticed the air pumps werent able to pump air. apparently the little stones got clogged up bigtime. i pulled apart my sog and lifted the lid and rubbed the stones and they began bubbling again.

i am assuming this was the problem. all the leaves are mega droopy now. i really hope she pulls though. thanks

how do ur roots look

terrible. stinking and rotting. the plants still drooping bigtime and leaves are turning yellow higher and higher up. i gave it enzymes and florashield and h2o2. i think im wasting my resources. man...has this happened to anyone else? is the air pumps clogging up pretty normal? could i have saved her if i had noticed it was the stones sooner? 3 days after i noticed she wasnt looking good i fixed it. has this happened to anyone else? any tricks to prevent it again?

i cant belive its another bust....

i got root rot one time from what i thought was high water temp

This sounds like root rot. Esp. if your air pump was off. In your shoes, I would cut clones, then give every piece of equipment that touched that water a hell of a scrub down. Soap it down, then use a bleach solution diluted in water. An airpump/airstone failure sucks, so preventative measures wouldn't have saved you here, but it might have bought more time. If you don't already, a half cap of hydrogen peroxide in your res when you change it out helps. Hope it bounces back twice as strong.

severeal things could have happened

1. Ph fluctuation try ph 5.9 for hydro. i have had some ph problems in my tnak it would spike 1 to 2 points per day and was runing ph at 6 to 7 and they were fine in veg but with bloom could be problematic but shouldnt be.

2. Every beginer hydros nightmare NUTE LOCK, my frst harvest i also didnt have a ec/ppm meter and over feed my plants and stuned them for two weeks top44 took me 58 days to finish. With hydro a ppm/ec is a must. dont ever go above 1900 ppm or 2100 if its a fertilizer freak. With hydro your control is in the res. if you dont mesure then you have no control. get a electronic ph and ec meter otherwise you can kiss hydro good bey and go back to soil.

3. Looks like a P or N deficiency in case of N defienceny your fucked... they dont recover from that. I am very sorry happened to me on my last harvest. 60% less yield than usual. I would recommend starting some new plants. Your roots are probably rotting and dying.

This sucks i know they only thing you can do is live and learn.

Here is something you can do, pump out all the water clean your res a bit, put in fresh water ph balanced water. Flush for a few hrs on just plain water, after that you put in 1/4 strength nutes and let it run for 2 to 3 days if she shows sings fo improvement then put in the regular dose. you can also try Revive by advance nutrients it helps correct defiencies but my guesse is you have nute lock and certain nutrients are blocked out, just do the flushing thing and revive and hope for the best. If in a week or two she looks worse move her of to the side and start some new ones while she finishes riping crystals cause she is not going to grow much more, maybee some density but thats it.

Most important in hydro is the EC then PH

hope this helps
