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.
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?
