The under leaves of all are fine but on the one plant that is the worst looking the tips are wilted and dark green. there was an accidental folliar feed shortly before this occurred but i shut the lights out immediately after, it was a diluted worm casting spray, very weak but it wasnt supposed to be foliar fed, not at that young. I was wondering if that might be the problem but if that were the case it should not spread. Do you think I should raise the lights up? they are currently about 3-3.5" above the tops of the plants. Thanks for all you help stinky
