That’s what I did last year.... tap water and miracle grow bloom. Stopped miracle grow in flower and used blackstrap molasses up until two weeks before harvest.just use tap water and stop tinkering with everything.
dont even use nutes until you can go one wholegrow start to finish on tap water.
thats my next goal
My yield was insane!!! For a first timer anyways. Yielded about 6 pounds on 4 plants.
