60 Plant Grow Setup

my room never drops below 69 and never above 81..average lights on is about 75 and off is 70

Just got back from the gym and there it is again. Plants are droopy as hell 2 hours befor the lights go off for 6. I hope they hurry up and re-adjust from that power outage.
I will take some more detailed pics tomorrow guys (i promise).

can i see a picture of this droop?

if you are concerned about mold, you can get a sulphur burner. they work great..

have an oscillating fan blowing at all times in your grow room... you probably do

cheers

Here are some more pics. I took quite afew close ups so you can look at some of the leaves that were burned from the spidemite spray a week ago. Now it looks like the yellowish burn markes are turnig brow. Im starting to wonder if its more deficiency than all burns.

Hey trent I also use fox farm ocean forest and did not use any nutes during veg,Im not saying dont use nutes but be careful that soil is packed with all kinds of good stuff. Get a moister meter only 10 dollars and takes all the guess work out and then youll know exactly how much and when to water. It kind of looks like a nute problem to me check this link out.....https://www.rollitup.org/view.php?pg=faq&cmd=article&id=588

Thank god you have pictures now! I believe the problem is most definitely a nutrient deficiency problem.

I could guess that there is a manganese deficiency from too much magnesium in which case you'd need to treat with any feed containing Mn(manganese), but I would trust one of the other more exeperienced growers on this site to help you out trenton.... I'm only guessing.

I'm interested to see what the problem is myself.

Good luck,
Stem

edited this out, dont want to recommend something that'll hurt em.

Looks like nute burn to me, where the lower leaf tips are going brown and the whole leaves look quite 'crispy'.

I would back right off on the nutes man.

I don't know if you'll need to flush. I hope not, cos 60 x 3 gallon tubs to flush is gonna use a LOT of water!

IMO it is undernute. Definite 'P' deficiency, which is rare in seed plants. I believe your problem may be PH, if not then it's definitely undernute.

i always have to go with ph..

trenton.. don't panic. they are far from horrible and you will still get a good harvest...

what have you been pH ing your water at?....

you need to change it... regardless of what you have been doing... if you have been doing 6.8, then you need to move to 6.0 for one watering or maybe 2... you definitely need to make different or more nutrients available for your plants to absorb..and you should do this through PH change rather than adding more nutrients...

cheers

PH of 2?! wouldnt that be crazy nutso???
what makes an acid more acidic other than its PH? for instence, if you toke all the PH down you had and mixed it with water and it was like a .2 ... it wouldnt be like a crazy acid that melts through everything... or would it?

I see heat stress also...I don't know if your lights are to close, but there is some raising of edges going on..The burnt spots on the leaf's, are they all from the foliar spray? There is burn starting from some of the tips, and that looks like over nut, but it looks like the worst of it is on the lower half of the plants..Hmm, The combination of crispy leafs on the bottom and wavy leathery leafs on top has to point to something solid. I wish I had some answers for you, but I would have to be guessing. If I was to guess though, I would think, #1 you sprayed with the lights on, causing spots #2 At some point, maybe even know, the temps got to hot #3 Your PH was off causing some deficiencies #4 You over watered, causing them to droop and get that leathery look. I am of course just speculating, while examining your pictures. I would not trip to hard on this, it is just a lesson for your growing credentials...

I think Gk was trying to say #1 thing to do and #2 thing to do... Don't ph the water to 2!LOL

Ok pH has been at 6.4-6.6 always. Yes I did use foliar spray (flormite) on the plants and the lights were on at the time. It took about 30 minutes to fully saturate all 60 plants. I left the lights on so I could see. after I was done spraying I turned the lights off for a few hours. Im sure that just by having the lights on for 30 minutes while I was saturating the %$% out of the leaves is what caused the burning. I did this 8 days ago. Maybe it was more on the bottom of the plants beacuse the plants were much smaller at that time so at that time it was actually near the top (if you know what I mean). Anyways, I think it should be normal for thoses leaves in particular to turn brown, get crispy or whatever becausee of the damage of the burns. The damage from the burns was causing those leaves to slowly dye off. Could this make sense. This is all a guess to me though.

If it was only burn you wouldn't have the wilting so much. I'm pretty sure it's a nutrient problem. Follow the above advice ^^ of garden knowm or skunk

Stem. Don't you think that the droopyness is a possible cause from the PGE being out for 30 hours straight. Im hoping that that is the problem and they will come back stable in a few days.

I see nutrient deficiency.

Try adding a small dosage of nutes, if that doesnt help them or makes them worse, then flush. Also, you have monsters man, bigger then most people... its going to use a lot more nutrients then a guy using fox farms ocean soil for plants that are under a 250w light.

THe roots are probably completely rootbound in that pot (which is good), and they have more then likely sucked all the nutes out... so add some more!

whats up t................still stressing????

one thing I did notice that I myself would probably do differently is water with less water more often...you said about a half gallon each.. I have the same size pots and I do 400 ml of water while vegging about every other day..and during flower I up it to about 800-1200 ml of water every second day...just my 2 cents though..

then I would try 7.0.. than going down to 6.0...

1. I have never seen heat stressed plants that look like that.. all the heat stressed plants i have encounters have leaves point UP.. no curling.. just pointing up.. the entire leaf

2. I have always heard more water and less frequency.. not the other way around.. and this has worked fantastic for me.. it looks like you have great amounts of perlite in your soil.. correct? this should take care of any over watering problems...

i am not trying to say i am right or they are wrong.. just adding my 2 cents...
