Is this a problem??

Iam just over 3 weeks into my first grow, wonder woman from seed. Plants seem very healthy and bushy and i thought i was doing really well. The last 2 days my bigger 2 plants have the tips of the leaves curling down like a claw(really only the bigger fan leaves that are on the 5th set of nodes not all) i dont really know if this is a problem. I have been looking on net but it seems it could be many things. I have ruled out nute burn because although there are a few tiny burns on one or 2 leaves most are very green and healthy looking.I was thinking maybe heat stress or my ph, my soil ph is just over 7, maybe i shoulkd try to bring it down to 6.5?? Or as its only affecting the bigger 2 it could be heat stress?? temp is about 81 on the tops of them big ones although i do have a fan blowing over them so they could be feeling less iam not sure. Take a look at pics and see what you guys think. Maybe iam worrying over nothing. Cheers

Curling happens. As long as there is a fan to move air through the plants it should be fine. Your plants are happy, they aren't stretching for light.

What's the temp in your space?

It also looks like a good time to to trim some clones off.

Yeah i was gonna do that this week,just waiting for my other reflector to turn up then my other space will be ready. Iam still very new to growing and i have researched plenty but it makes me feel better asking and getting answers from you guys. You recommend taking clones from the bottom?? because thats what i was gonna do?

It's better to take from the bottom. I get air moving down there and prevents some powdery mold problems. Good luck!

damn, my wonderwoman seeds from nirvana won't even germ. yes, i've tried all the methods. nice lookin ladies though dude.

Had 5 germed using paper towel in a tupperware container, 4 cracked within 14 hours or so ,left for just over 24 hours and still just the 4 but planted all 5 , the 5th one did sprout about 4 days after. Sorry to hear about yours bro,iam hoping they live up to their supposed yield!

no joke there. yea man i ordered 3 10 packs of the wonder. two weeks ago on the 9th i germed all my strains, 15 of them being wonderwoman. only 4 popped and once planted, showed no signs of growth. the other 27 girls are doing great at week 2 though.

i started germing 5 more wonderwoman 2 days ago (paper towel method) and they look a little swollen but are still not poppin. i think i'm going to contact nirvana, see if they can help me out. on my other strains i had like a 98% germ rate. only one northern lights didn't pop. was really looking forward to the W.W. strain though, pretty disappointed.
