Plants got burnt with sulfur burner

I have 6 plants in a 4x4 tent. I was burning some sulfur as a mold, pm preventative and ended up burning my plants. I found these pics that look exactly like the damage on my plants. I just changed the light cycle to 12/12 on june 20th and I already have preflower hairs. What should I do pick off all the bad leaves ? Start giving them 18/6 again and grow a couple weeks so they are fully recovered when I start flower again? I have already picked some leaves but it seems like there is residue still on the leaves. Should I spray with water? Any ideas anybody?

I burn sulphur often and never experienced that. Your leaves must have been damp, high heat and lights too close to do all that. Pick off all those crappy leaves because they arent doing anything. Spray water and all that sulphur residue will form sulfuric acid and really burn your plants

Prune and go back to veg until you get healthy leaves again.

Dam thats kinda what I was thinking. How long does it usually take to start revegging? It has been 12/12 for 10 days.

Takes about a week to begin revegging. Maybe a little longer.

Ok thanks bro
