What can I say.... I've been very careful not to over-water, I think. I can't figure out why this is happening again! It looks like salt burn to me but I really have no clue. I just poured 10-gallons of water through the container hoping to leach it out and hope it recovers...
I'm about ready to forget using any fertilizers at all and just water them, like they did 100-years ago.
If it is too much M-gro, will the leaves return to green or are they toast?
Any suggestions?
