What's going on day 15 veg

Hello I have 10 plants at 4 different strains experiencing this problem what is going on and how to fix it..
Thank you

Burnt up from lights

I have 2 nextlight mega raised to the roof of my tent they were closer a week ago when I noticed it is this too much light or will it fix itself

No clue

How far away

It's a 4x8x6.5 so about I'd say 5ft possibly over

..

So a week ago how close where they

Was about 40 inches when I started them from t5 I have epilepsy and I'm hoping at 1 point after a seizure I didn't do anything to the water or lights ect because I was out of it for a couple days

If it's the lights I turned off 1 but my question is is it to much for flower if all the way up

You have issues, looks like you burnt the tops

But if u say no, then I'm not sure

There not dried out on the tips and after uncurling they open nicely

I don't know

Well that big fan on the floor is two close even on low you need to get that back far as possible

I unplugged 1 light moved the fan will see what happens.
