Light burn?

What do you guys think? Too close to the lights? This is the only one out of four plants that is showing this burn but it is the tallest of the four though. The strain is Purple Haze about four weeks into flower, hydroponic with three LED lamps. I let it stretch too far and it was about 12 inches from the LED before moved it a little farther away. I've had another strain grow closer with no issues but figured this might be more sensitive. I have multiple fans on timers both circulating air and exhausting the tent, with another timer introducing Co2 to get the PPM up to about 1200 PPM until the next exhaust. Let me know what you think or if I'm pretty close in my guess.
Thanks!

Yep

heat & light

I figured. Do you think that those tops that got burned will develop funky or is it early enough for them to pull through normally?

I think they should be fine for the most part most of em got some green left to give back so I would imagine still ok , jist my 2c

Thx guys
