Leave curling in on themselves

is it possible to post a picture of the hole plant ? would like to see both top grow and bottom grow

to me them leave`s look dried out/under watered ? and the little yellow could also indicate that or a Mg deficiency

yea a strong fan blowing at them constantly can give em wind stress (I never point the fan directly at em)

also temperatures on 73F is a bit low actually, but a RH on 40-50% is more or less perfect, even in Veg, I have had nice looking plant at 28% RH

a 80% pure Indica .. with out curling leaves

Very nice Slipon, looks to be extremely healthy. was she grown under your led's or is that just for flowering. I'm really considering going with some led's to outfit my new flower room. I think the heat would be alot easier to deal with off some led's rather than two 600W H.P.S. lamps. I guess I have a shit ton of research to do. oh well, keeps me out of trouble. Good luck, Good grow, Be safe, out.

thats the Big one I now have in flowering, she is like 3-4 week`s old there I believe, and have just been under a few 49W T5HOs (6500/2700K)
just plain rain water in my own SS mix but actually had a bit of a struggle with low RH (also why the leave`s might hang down a bit on them pic`s) had like 28-32% in early spring do to the cold long winter I believe, even I got dry skin got a humidifier and got it up on 40% of so, now I don't need it with hotter temp`s, is steady at 40-50% now with out the humidifier

Where I live I have a humidifier season as well, I just pull her out time her to get the humidity I want and put it on a timer. 40% is about as low as I like it, after that yeah the humidifier comes out. Are you mainly an indica grower or is it just something you have for night time or something? I like a good sativa or at least a sativa dom strain for the day time. I love my indicas at night though. A sativa will have me up all night reading and being busy. Even if I do smoke a gram of a heavy, heavy indica I usually only sleep 4-5 hours. I'm a very light sleeper! My friends call me puff the magic dragon and all kinds of goofy names cause of how much I smoke, but I have to medicate before and after I eat or else I can't eat in the first place or will get sick right after. As long as I smoke though I'm fine, really is quite frustrating considering I don't live in a medical state. I'm not going to starve myself to death though because my government don't recognize the fact that this plant is keeping me alive, FUCK EM! Oh well sorry for the rant. out.

Hey everyone. I am growing in FFOF and FFHF. I do not feed anything except FF Flowers Kiss, Boomerang, and Microbrew, which I only fed once to them. Ph going in is always between 6.2-6.5. A few leaves are curling into themselves on 2-3 plants. They are under a 1000W MH. 30" from the light. Fans are always oscillating on them. Here are a few pictures:



I have read that this could be a mag deficiency. In my soil I mixed in 2 tbls of dolomite lime 2-3 weeks ago. I know there is mag and cal in the dolomite lime. I dont want to add anything unless I know 100% what is causing this. Temps are always 73ish and Rh is 55%. Thanks everyone for taking a look. Also some leaf stems are purple.

Sorry about the double post. I screwed up the edit and hit save. My bad.

If your temps are like that then heat stress can be ruled out. Looks like you have a fan blowing directly on them. If your leaves or moving more than a slight wiggle reposition your fan. The curl shows stress. As far as humidity no its not the issue I run my room at 35% and there are no issues. Wind would be my guess. Low humidity if not looked after will look like the plant is dying. Each little point on the leaf will start to crisp up and eventually they will have brown crispy edges. This does not happen above 45%.

Thanks everyone. I really appreciate the help. I have enacted the ideas. BTW...the fans were way too close and doing more that just a wiggle. Thanks agin everyone. Slipon...I'll get a picture in just a bit.
