Is that a light burn?

so i went to see my babies and i found this ..

i added a fan after i saw this and moved the hps up a bit! so will it be ok?

It's hard for anyone to answer without the exact lights you're using, what distance, temp and humidity at the very least.

Nutrients at what strength in what medium and what ph?

HID will usually 'taco' the leaves from heat before you see bleaching. Need some more info to help.
