I was Using Schultz Orchid 19-31-17 for 3 wks of flowering before noticing the problem, now I have switched to Flora Nova Bloom. Someone said I was given bad advice because Schultz has allot of shit in it. I'm in mid 4th wk I have watered twice with Flora Nova Bloom, last night I flushed and gave half strengh Flora Nova with H2O2, some perking up this morning will keep posted.
