That is a nice place you got for your babies bro. I like it. I have just one option rather than having to build an awning....or replace the doors with solid core doors...you can wrap the inside side of the doors with an insulative material called Reflectix....you can pick it up at home depot...and the shit works miracles...but if you need an excuse for a project....well then...hell yes....bigger awning. but if you wanna save some cash then it will do the trick...or hell...run that ac all the time...problem solved....either way...just a thought....but the place looks great! those plants will be back in no time.:blsmoke:I have the faith

i had the same prob. bump the humidity up a bit, i know this is bad for rot but i bumped mine up to 70% for a couple of days and they look like they are back in to pump mode instead of die mode, worth a go, mine perked up in 24 hours.

I agree, Leaves do not usually recover once the damage has been done, but *in this case* since it looks like they got thrown in the oven for about 5 or 10 minutes, maybe giving a little bit of humidity in controlled doses over the course of a couple days to a week may help to un-dry the cooked leaves.

Be VERY careful if you do this. You don't want any mold or bud-rot, or any degrading of THC cyrstals this close to harvest. There may be something to humidifying the leaves, maybe they will at least quite drying out any worse, just take it easy. Just a little fog at a time, don't let any water vapor penetrate the buds. Try and humidify just the leaves. Thats all I can think of. :peace: out!

they got pretty bad. we had a heat wave for 4 days. my temps stayed in the 90's. i found a portable evaporative cooler i had stashed away. i set it up in my doorway when the lights were on. along with a small AC in my main room and a large fan. i stayed up every night until after 2am when i could finally get it all to cool down. the temps dropped yesterday afternoon. it cooled off in the evenings a little. they seem to have stopped curling now and are showing vigorous growth again. those leaves won't be straightening out. they're almost crispy. i'll get some pics up tonight if i remember.

I only skimmed this thread so I don't know what everyone said but it can't hurt to throw u my 2Cents.

Upward curling leaves are due to heat stress(as everyone has poined out)
or a magnesium problem. A Mg problem as you may or may not know starts with old leaves first and have signs of yellowing in the veins.

AN MG deficiency shows itself as the leafs form a "v" as if they are holding there leafs out to the light waiting for a handout of extra MG:mrgreen:-it's one of the easiest nute problems to diagnose. Curling leaves can be a number of issues from heat stress to nutrient lock to low ph and others as well.

I read the first 5 pages and I too think that it is heat stress along with a air-circulation problem. I'm saying that cause you stated in your first posts that the problem goes not happen consistently throughout your grow room. I see the 2 fans you have in there, is there a chance that they were not on for any possible reason while the curling up happened?

no, those two fans are always on. well, one of them. the second comes on when the lights come on. i do have an exhaust fan that is exchanging the air in the room 4 times a minute. :mrgreen:

i have my heat down to the mid 70's now. :hump::hump:
things are looking good.

what about using revive by advanced nutrients... anyone use it before for this issue? about 8 of mine are dealing with severe heat stress from the past weekend.

I guess that could be heat stress. But I've seen pictures of white widdow and others that were deep into flowering, and their leaves were curling up like that. I think some plants just do that in late flowering. As long as they dont crisp up I'd think they're fine. But I've never heard of giving veg. nut.'s while flowering, but hell your grow looks way better than mine. So what do I know. Good luck.

If I can get mine to look half as good as yours fdd I'll be a happy first time grower.
It's making my mouth water just looking at 'em.
Hope thats the last of your troubles.


Feel free to browse my journal, comments or advice and suggestions all welcome, but that doesn't mean I'll take heed. The more ignorant we are the more we think we know!!!

If your nutes don't have mg in them then the answer is yes--If you use RO water source check for cal as well----I recommend a cal/mag product if your nutes don't have cal/mg in them---some growers misdiagnose plant/nutrient problems due to the fact they don't realize that the plants need and use as much calcium in there growth cycles as N-P-K. Always check your labels and add-up all ppms/ratio's of each nute and nute additive to assure you have a balanced and complete nutrient profile.

fdd... you might want to look into buying some sort of silica additive... it really helps the plant tolerate the higher temps... there are lots of products out there, a lot of them are foliar sprays... but i like DE (diatomeaceous earth) because you can mix it in with your soil when potting, acts as a natural pesticide, and can also be mixed up into a bottle with water and be used as a foliar application...

best of luck wth the rest of the summer friend =]
