I mixed a small batch of Fox farm big bloom and used it as a pk booster. Also top dressed with fox farm ocean Forrest and 1 tbsp of dr earth Flower girl and 1 tbsp of dr earth all purpose 4-4-4. So far I’m liking the results and the plants look very happy and healthy. I do have a light green color to them but I believe that is just the new growth green that all plants get. I could be wrong but I don’t think so here. PPM 1188 for pk booster.
