Light burn or something else?

[Teag]

The leaf in the 1st picture is directly under a COB and was wondering if it looked like light burn to the experts. I'm flowering two plants right now. I've had a magnesium deficiency which seems to be getting better after I've added some cal-mag to the water.

Grow space:
2' x 4'
4 COB's 32" away running at 2100 ma

1st plant is Bubba's Gift and the 2nd is Glueberry OG.

Guesses on how much longer to harvest?

Couple weeks longer then the leaves will hold up?

Just a thought it kinda looks like your feeding too heavy with the leaf tips looking like that though not too much cause its barely noticeable.

Like hybridway2 said you look a couple weeks out and your pistils have receded and changed color. I wouldn't even worry about it.

I decided to move the light up an inch. I guess I'll just be crossing my fingers until harvest. Thanks!
