Help identifying problem

hey was doing some reading on symptoms, but I can't figure it out. I can't tell what the problem is.

It started like 2-3 days ago, first noticed tips seemed a bit brown and burnt. I cut them off. Then a few more burnt tips came up and some leaves started getting light green on them. I'm not sure what it is can someone help here are some pics

Either nute burn or light bleaching.

I see Mg def due to some yellowing between the veins. If you got burnt tips and edges, I would feed half-strength nutes and twice the volume next time for heavy > 50% runoff (modest flush).

I haven't seen anyone manicure their burnt tips/edges like that. If you leave them on it will help people assess what's happening. (But, I guess it's not hard to imagine what the missing pieces looked like. Seems like stress though, cutting leaves.).

As for me it looks like mg def as said @az2000.

Id say nute burn. See how youve cut the tips of the leaves off cause they died yet the rest of the plant is dark green. Probably because they got fried. How much have you been feeding it?

Thank you guys for the help.
I have not added any nutrients to the plant, just add water. This is the first grow i have, and I wasnt sure what to do so I just clipped the burnt looking edges. Will leave the plant as is from now on and let it heal its self. Watering atleast once a day, or until the top soil looks dry. Its about 6 inches away from 2 cfl bulbs, with a small fan on.

Why are you cutting the tips off? You're just stressing it more

I was going to say high pH causing Mg lockout...thus an Mg def.
