How close you keeping them currently? I keep my aircooled 600's about 14-18 inches from my tallest tops in flowering. I let them chase it in that they are roughly 16 inches below the light and during the two week stretch, i raise em up as needed to maintain the distance. Having good airflow across the canopy top can prevent would-be burns or heat buildup.
you will remember this excitement for a very long time 
like your first kiss but with THC lmao
I had it 6 inches away and no sunburn... I think it's the micro labs I have been putting in. It says it helps with photosynthesis.they don't seem to have any signs of sunburnlittle beasts!!!
You have to make them your subs! Lol I got a sample from my local hydro dealer that seemed to help them.
No and you came at the perfect time. Next week we start flowering.
I was worried cause I have been topping them and thought maybe I did to much.
