Hey SB, I kinda have a grow journal in the indoor forum (oops). Everything was going good till I moved my plants under my HPS, with my lights at 12/12. Moved them into a different room, had my light too close, burnt some leaves. Moved light 3' away, still noticing some burning. Been giving them same nutes through out, about 3/4 strength of suggested use. Misting them with plain water because of heat. Dirt. My nutes are a three part system.
1. 1-2-5
2. 2-0-0
3. 1-4-5
1 and 2 for growth, and 2 and 3 for bloom. Chemical. Still using just 1 and 2, 3/4 strength. They are in the same room as furnace, maybe a little carbon monoxide (don't know if that affects them) in my garage. More info on my "Second Try" thread if you are completely bored and are watching the paint dry on your wall. But I think that is the jist of it.
