is this nute burn?

Hey everyone, this is lowryder #2, and its on day 55. is this nute burn? I'm using tiger bloom every second water. Should i be worried?

Looks like it's only the tops? Maybe the lights to close? Dosent look like anything to worry about, TB is strong shit tho maybe back off the dose a bit

I was thinking it was the lights, but i moved them up a little bit. they are cfl's so they don't really get too hot. I may just do straight water the next 2 waterings just to help.
iTLL Proabbly be done by day 70 I'm guessing, so hopefully there good until then. Its just the tips like you said, the rest of the plant looks healthy!
