Nut Burn or Heat Stress? PH Burn?

MG soil (I know, I know, it sucks. I grow other things, too, so it was handy).
Is it nut burn, heat stress, or pH burn?
CFLs, 334+ watts.

What's wrong with my babies?

HELP!

looks like nute burn, are u feeding it if not its the soil doin it its to high in nutes,tranplant into some differnt soil if u can, also u can try to raise the cfls a few inches just to make sure its not that but im sure its nute burn

Def transplant them. That soil looks like shat and only half that container is full.

Freshen everything up and you will see improvements.

Thanks for the help! Will do ASAP

if all u have is mg soil i would put it all into a big bin with drain holes at the bootom and runs alot of phed water through it to helo wash thosde nutes out and then use it,

I changed to an all-organic soil, the ladies are doing a lot better. Thanks for the help!

what type of soil u usin now, but whatever it is sure they will like it much better
