I've successfully grown bag seeds, kushage and sage so I thought I had some idea of what I was doing BUT evidently I was wrong. Hydro, T5's, 4 gallon bubble bucket, Tent, gh nutes. I've now managed to kill 3 sets of seeds. Kill one- Vanilla Kush- Germ ok, then after first true leaves Root Rot killed them all. Kill two- Shaman- Germ ok then put into system with too much (I thought) h2o2. They never went past tap root and tap root kind of fell off. Kill 3- I honestly don't even fkn remember what seeds cause I'm a lil stressed by now- basically same shit as above. Between successful grows and this shit I changed from rock to clay- This shouldn't cause this, right? I mixed the h2o2 correctly after the second fk up. Please please please! Somebody give me a clue on what I have done to successfully kill all my good seeds.
