Light burn?

Growing in soil using jack's tomato feed. Not checking ppms. I burned the tips a couple weeks ago, no big deal but this weekend some top leaves are brown and curling up. Light was about 1ft away and canopy was about 97F. I moved light up and now it's about 80F.

Light burn is what it looks like, What kind of light?

i think so too, keep the light up where it is and see if it gets any worse. i think you ought to be alright now, that doesn't look like a deficiency. its hard to tell looking straight down, do the hairs on top of that bud seem bleached out?

Wow i see so many fasciated colas now days! That shit looks trippy lol.

I've had crispy tops like that when they stretch too close to the hood, i agree with IR stress.

heat, uv and ir, but cool polyploid! hope you didn't burn the top too badly!

The poly one got the worst of it since it's the tallest.
