Curling leaves ... problem? I added some pics....

[Yota]

Pretty much every plant in my group of 20 has a single curled blade on its leaf (or 1 or 2 more). It kind of twists. So whats going on?

I'm thinking it may be because my ph lvl is around 7-8 and is too high. I'm working on lowering that. Has anyone seen this before?

I'm hoping someone can shed some light for me. Thanks in advance for the help.

I'm kinda new but that doesn't look like Ph to me. Check FAQ. Looks a bit like a lockout to me......maybe MG?

have you got good ventalation and a fan if so then its lack of water 200ml every 48 hours. you're soil mix looks very dry

im using ebb flow system so the top soil is dry yes, but the bottom half is moist. I know its running a bit hot in there, so i added an oscillating fan yesterday. Could heat cause that over Ph problems?

NO heat wont..some nutes escalate ph ...try adding your nutes 24 hrs before phing

get a themometer keep the temp no higher than 27c and no lower than 18c. if you've just put a fan in yesterday that will be your problem. heat has no effect on ph perlite has a ph of just under 7 perfect for cannabis so ph problem could be compost or nutes you're putting in

well i did have a vent fan and some air holes, but i added a osc fan. but it def has a diff temp feel in there. Isnt 7 too high of PH though?

7's the highest you want to be with soil
try to baby her down to a 6.5 or low 6's..gives you a buffer on problems
