18-07-2021: Not everything as hoped but we are almost there with my worst round ever. But there is some red showing on the Red Hot Cookies so I am allright because that is all I wanted to achieve. Harvest won't be great but I have almost achieved my most important goal. Harvest a hydro round. Lowered EC from today on to 1.2. Will start flushing next week.
@Ze1ro, Very true. And to be honest I like to experiment so it isn't a bad thing at all something goes wrong. I have learned that you can spray H2O2 (12%) directly on the roots to remove mold. Yes it does slow the plant down but it will be capable to survive.
