I was wondering if anybody can give me some advice on light height. I’m sitting at 31 inches from the top of the canopy and I’m starting to see yellow tips. Leaves are folding in a tiny bit and not reaching or anything. Would someone recommend lowering it, putting it higher, or keeping it there based off the pictures ? Tent is only getting about 73 degrees so I don’t think there should be too much light heat stress but I’m not sure. They are in a 3x3 tent.Thanks in advance.
Very slight nute burn looks like. Def. nothing to worry about. Keep on eye on them over the next week.
I would check and recheck to make sure your ph meter is calibrated.
You might want to back off on nutes a little.
Looks great! 
Thank you, I haven’t put any nutes in, I have nature’s living soil in the bottom but that’s all. Not sure if the roots are just now getting to it then. @spyonyou
I agree with @HappyHydroGrower , that light can’t hurt those plants, specially at 31"

I think your plants look great. As @HappyHydroGrower. Mentioned very slight nute burn. Nothing to worry about. You know your soil is doing it’s job plenty of goodies still left. You could probably lower your light down to 27 inchs with no problem. Looking good !
I agree with kellydans, nute burn. Pretty normal to see some as the roots find the good stuff.
i was looking at the first pic and i thought OMG, it has to be the lights. it made your poor girls all blurple looking. but then they look ok in the other pics
