I managed to over fertilize my soil with my poor watering skills.
I hope I can do better next time using EC meter.
I don't really get how to control/balance my plant's NPK intake with those formulas bg 4 - 3 - 6, bb 2 - 7 - 4.
I think when I cut one and add another that leads to imbalances. Hard to tell.
