firstly they don't need repotting yet, a few days maybe, and the burning looks like water on the leaves and burning from the 400w MH. SO no worries just hope it don't get worse, otherwise plants lookin nice and nice choice M/kush

thanks for the fast reply.. i was thinking it may have been water on the leaves too.. but just wanted to make sure.. how about those little whiteish spots lower down on the same plant?

i just find it odd that only that one was burnt.. unless it was by water which makes sense

right now the light is about 42 inches away.. however they are in a tent with all reflective material.. and i cant lower it due to the cooling system being up there

No

Thats most likely why then. stop feeding them nutes, the soil will have every thing the plant needs, just give them ph`ed water. Likes been said wait a few days to a week Repot them and give them about 2 weeks before you start to feed again.

If you repot 2 -4 times before you flower you should never need to use any Nutes in veg... just Free tap water
