Good picks! Got a problem PLEASE HELP!

What is going on with this plant? Please tell me its not mold. Its only on 1 little branch on one plant, its a little branch that should of been cut a while ago for a more SOG style.
Im at 65-70F, 55-60% humidity and my rez stays at 65F. Im only week 2 and 5days into flower. These ladies were 8in tall when I flipped them, to 12/12, they are 30in now! IN ONLY 2-3weeks!!!!!! Its healthy growth, this plant is a power plant:Fruity Chronic Juice. I did my research and this strain is very mould resistant, I am putn my 6in fan/carbon filter in soon to bring my humidity back to 40%, up until now I just stapled a light prof black canvas over an open window in the room. (i used to have a lot more lights in a bunch of tents in a garage) so this isnt my first rodeo just my first with Hydro.

The first two photos are the concern, the others are just of my grow in general. They smell like huffing a bag of flowers fresh cut from a florist, crystal clusters way too much for only 2-3week, and just thick and hardy! I Fucken love this strain. I have played the strain game for the past three years looking for one that fit me.


THANKS TO ALL, HAPPY GROWING

Looks like caterpillar ,get a light in to the branches a get that sucker out.

To me that looks like classic Phosphorus deficiency. What Ph are you running at?

Your right it does look that way... my PH is at 5.5-6.0 (I use the GH drops in a vial) Its not 100% but has never let me down. I am on the tail end of my rez change, I have been topping them off with 1/4 strength nutes for a week now. Tonight im doing a drain and refill. I know the nutes im using, there should be NO way Phos. is locked out or lacking...UNLESS AS THE PLANTS USED WATER THEY LOCKED OUT OTHER NUTES BY MAKING AN IMBALANCE. When i noticed this the rez was half empty!!!! Thats the one prob with hydro is water vapor! Either my 6 30IN plants use 10gals of water in three days or its evaporated and waisted.

looks like powdery mildew

Phosphorus, caterpillar, powdery mildew? 3ppl 3dif answers.

If it is powdery mildew or gray mold (botrytis) what should i do? I was thinking of amputating the affected branch... im in flower i dont want to spray em

Ive never seen mildew like that but thats not saying much.
I would do complete res clean change and take it from there. remove the leaves that are 50% or more affected.

well thanks to all. I do not believe this is mold. My RH never got above 55% and I have always been too careful about mold. Well not TOO careful but persistent. I think it is a Phos. def. Im am doing a complete rez change tonight after work and I boosted my fan up and got RH down to 30%. Botrytis can be stopped by lowering the humidity and a lock out or lack there of a nute can be fixed by a rez change.

I would be on the look out for Thrips and leaf miners if I were you.....

Is it just one plant or are all affected. Why I ask is while it does look like a phosphorus def it almost looks like maybe wind burn as well I've had a plant that was doing that and moved it out of fans blow and it stopped. I'd perform a res change and see what u can get back in order.

I have had a HUGE problem with Thrips before. These are not them. I dont have little miners cruzin around eatn the top of my leaf an poopn it out right there. These is not a bug infestation.

It was just one plant, I noticed it on the others but not bad. You know I was wondering if it could be the fan. I have a normal osculating desk fan sitn on a upside down pot in the middle of the room trained on them. Even on the first speed it fuckn blows them around like rag dolls! That would probably be why i saw just one little wilted fan leaf last night during the rez change. It is probably the fan, I had a fan blowen too hard on some plants once and it almost completly stopped growth. This is probably the answer! Thank you.

I Grew FRUITY CHRONIC JUICE (from delicious seeds) a couple of times, and a few mothers for cloning , and would get that on a few of the lower/very bottom leaves, although not all torn up like that.. I didn't let it bother me, the rest of the plant was Full and Lush, and they finished GREAT!
