Looks like serious nute burn to me. It's natural after a burn for the leaves to die, in time...sometimes it's a slow death, other times it's quick. You flushed them, that's good. I've found that some plants just do not like fish emulsion. I had three Afghanis that loved it and one that just couldn't handle it. How old are your plants? I'm finding more and more people have to wait a little longer before giving nutes if they are using CFL's. Keep an eye on their new growth, as long as that's ok, your plants should be ok. Peace!
HiProGlow Reviewed by HiProGlow on . diagnose this PLS!!! Ok... I posted in the grow lounge a little while ago about normal growth, my baby was doing fantastic considering her conditions. The set up is a closet, bottom for veg and top for flower, the bottom is 2' 8" X 2' 11" and 35" high. Top is 2' 8" X 2' 11" and 5' high. Lights are 6 27 watt Cfl's in a redneck, hillbilly homemade hood :D (pics if requested) as well as one being used for sidelighting, they are at least 4 inchs off the top of the plants. Temps in the bottom range from 73- 80F Rating: 5
