Actually Sal my soil ww has been under flouros right up until we turned her AND has had several applications of LL with never a single problem (pss....don't know about yours Rock buy my cfl's are about 4 inches away from the plant.) NEVER a problem.

BUT ...have DEFINITELY had problems with mh lighting and burning. Rock....I'm booting your theory to the curb.
Weedhound Reviewed by Weedhound on . Foliar Feeding and Liquid Light, Part two: The Reckoning. Intro Itā??s been suggested that we need a good thread about foliar feeding in general, and a product called Liquid Light in particular. I agree. Iā??m not sure how good this thread will be but Iā??ll try. I was a little surprised when I started asking questions around here about foliar feeding, and it was like deer in headlights or something. Huh, whatā??s that sonny? Speak up a bit. Folgers feeding? Why we were doing that thing with the coffee years ago. No gramps, foliar feeding. Rating: 5
