What could be causing this?

Hi guys,

just started my second grow, first grow was with cfl's. Iv upgraded to hid lighting. I'm currently running a 250w MH. All 3 of the 4 plants are fine. All in biobizz all mix. All auto flowers. Everything same as last grow but this one is running higher temps and lower humidity. Not sure if its that causing this or something else. Any ideas? I'll post apicyure below.

By any chance did you splatter any nuted water on the leaves?

Na, but I have had a plastic bottle cut in half over them to keep humidity up... You thinking the moisture could of magnified the light...or you thinking nite burn?

*nute

ditch the cup humidor. Its not needed, that plant is very ready for natural elements. It really looks like wind lash. But I'm going to bet its ph related. Especially how dry your soil looks. What are you feeding, at what strength, and how much are you watering when you do. Whats the size of the pot? Are you feeding with tap water, ro, well etc. all those things can help us better diagnose the issue.
