Is this Light burn ??

First grow and this is my 5th week. This is the only place i see this so far. Does anyone also think its light burn or something else.
thanks

No heat makes the leaves curl upward. Your good, sometimes flowering causes yellowing because the plant is using all its energy to bud instead of grow leaves. But make sure your not over feeding to! You will need to flush after 2 weeks, I'd say at week 7.

test heat by placing ur hand at the top of ur canopy (top of plants) for 30 secondsif hot on hand move futher away, (rule of thumb) hope this helps , looks to me over fertilizing mayber to much water

this is pointless to do i can hold my hand on my glass and not feel a thing so your saying to drop my light right on top of the plant no it dosent work that way

Grorite is right, general rule would be see if ur hand got hot but what if u have a different heat tolerance. I think check ur ph bro could be the start of a deficiency in my opinion as you havent stated ur environment is out in anyway. Goodluck

Umm not quite I got that last part but . I have yet to check or worry 1 I Oda about my PH since day 1, No offense of course, I know its very important and yet I have not bothered once to check on it so I doubt I will start now.
As far as the hand under the light rule goes.... Not a huge fan. I have done that dowzens of times for minutes on end to satisfy my own needs and nothing , I have the light 9" away and am sick of obsessing about finding the exact perfect height for my light , as long as my babies like it , I like it.

Environment- ummm ??? Soil ? Tent grow, that kind of thing ?

Ahh-
I am using Biotanical 135 bloom - Just last feeding did Igive a full dose of 25 ml / 1Gal. I also have used MOAB but only in weeks 1-2 and again in small small dose last feeding.
I feed them once a week and water 3 x a week .

Here are some more pictures taken same day. Mostly healthy in my mind.
