WOW what a clusterfuk of confusion in these replies.
Does anyone try and be specific?
Instead of saying I tried Koolbloom and got hermies, try and tell us about your whole grow. Starting out with what nutrients you use, followed by what Plant enhancements, followed by any other useful information.
So I have been using the Flora series from GH, using DWC hydro with an airstone at the bottom. Once I started to switch my lights to flower, I started with Floralicious Bloom, Liquid Koolbloom, BudCandy and of course the Flora Bloom, Micro & Gro. So far No Hermies, I am at week 5-6 now.
So far I like what I see, and buds are starting to plump. I plan on stopping Liquid Koolbloom and starting the Dry Koolbloom for the last couple weeks.
From talking to other "Caregivers" I have heard of many reasons for Hermies, and the reason most given is that somehow light entered the room, whether a crack in the drywall or maybe a light from a power supply, but have never heard of Koolbloom causing Hermes.
Here are my pics most are purpkush and william wonder cross, please bear in mind I have no xp in growing and have been dealing with overnutes and spidermites. Which "AZATROL" helped rid them mites. Hope you like!!! Good Luck with the HERMES.
