Paper thin leaves, cracking, turning into dust...

Everyone was like "you're worrying for no reason!"

WELL LOOK NOW!

What the hell is this?

It crumbles to pieces when I touch it!!!

Great so which one???

Tell us a bit more about your setup. What is the pH of your nutes, what is the EC, PPM etc

I'm using DWC.

This all started after I treated my root rot with H202.

Even when they had root rot they looked literally 100% healthy.

My pH is at a constant 5.8 -- I monitor it twice daily.

My water temp 72 farenheit

My air temp is like 78 farenheit

ECM PPM - Don't have the equipment


Also I cut off all the REALLY damaged leaves (not totally just the really damaged parts). My thinking that the plant would concentrate on its healthy parts rather than trying to fix its problems.

was wondering how long u had ur plants goin before u they started to crumble like that, just picked up an ag last night and am excited about the whole thing just a small bit skeptical

Well it looks to me like fertilizer burn. But thats just a guess. The EC reading would tell you if your nutrient is too strong or if there is a salt buildup. So without that the best guess I can give you is to flush if you havent already and start with a new batch of nutrients.
Check out http://www.ganjaguerrilla.net/Album3.htm as well for pics of nutrient burns.

What kind of lighting do you have? How close is the light?

I flush daily...I think it's a nute deficiency if anything.

What do you think about my cutting off the really bad part of the leaves???

Good idea bad idea?

Could it be that I'm using tap water???

They've been perfectly healthy until like 3 days ago.
I'm flushing daily now and almost running out of nutrients.

I wanted to go into flowring next week...but the growth has been stunted for three days...before all this it was growing exponentially.

250W CFL's like 8 inches away...

Definitely not heat stress.

Does anyone think N toxicity???

How to cure this?

always get rid of bad leaves. it looks like nute burn, nitrogen if i had to guess by looking. what are you feeding it. whats the NPK of the food. whats the PH of your tap water?

so cut the whole leaf down to the stem? what if there are already preflowers that look health at the elbow of the clearly dying leaf?

No pre-flowers here yet...

Damn bro I'm gonna have to subscribe to this thread. I have the same thing going on with one of my babies and it's in soil. I got the same first response you did from that same dude. Please let me know if you come up with the solution.

Yah I fixed my problem, it was actaully a few things that culminated into this...

I do't have a humidity reader, yesterday my boy brought one and it was like 10% where I'm growing...by the way I'm indoor hydro.

Anyway the low humidity, plus the dry heat coming from the lights, and to top it all off I had a Nitrogen defeciency.

I would definitely check your N levels and humidity...with hydro its a little easier because you can just flush. I don't really know how to help you cure your plants in soil. Try posting in one of the soil forums.

i never started nutes on my cfl soil grown is it too late, i mean its flowering now on a 18/6 starting 12/12 tonight.
