I've been using fox farm mixed in gal jug for two plants. Seems to be working great in 5 gal buckets. I could never get an answer on how much for 2 plants picture of my 2 girls
I’ve been mixing the three together in a gal jug for years, and my well water is 7.5, so I add a little less than a 1/4 tsp of citric acid which lowers it to about 6.5.
