Whats Goin on?

Ok without knowing ppms (too high...too low?) I'll offer two thoughts. I would not want my plants in 6.4 ph for that long but it seems to me you would have seen the issue beginning before tonight if the problem was ph.......

I'm assumong you've done something about the temps and your plants....no more 102 degree days and nights?

Lastly.....plants sometimes DO lower their leaves at night when they "sleep" If you suddenly interrupted the darkness they may look like that simply because they are resting their leaves. If THAT is the case they should perk up pretty quickly with the light on for awhile( and by pretty quickly I mean within an hour or so). If they DONT.....I'd then guess ph or ppms.... check both right now and make sure they are normal.

yea i got the temps in control, dont kno, ppms (np ppm meter), but i dont think they were resting the branches are weak and looks a lot like overwatering/drownding but there not

well one revisor i added a bubbler and cut down like on my nutes like recomended, and that one is fine, but i dont really think its a nute prob on the other bc ive used this nute recipie before with no problems

If it isn't "waking them up" and it isn't your ph.....nutes would certainly be the next thing I'd look at.

And Jimmy.....treat yourself to a good ppm meter for X-Mas. ;)

I HAVE NO IDEA WTF THAT WAS BUT I FIXED THE PH AND THREW IT ON 24/7 FOR A DAY AND THEY LOOK FINE NOW
