No…I use promix. You need to go by the weight. Let them dry out (seedling’s are different than this). And then give a full feed. I use 5 gallon containers, so a full feed is a gallon. Don’t feed again until the pot is super light. In full flower they usually get fed every two or three days….veg starts slowly and increases. Have patience.I'm using sip buckets and HP promix biofungicide mycorrhizae high porosity peat based...... Twice a day should I be doing that?
