I know the lucas formula does not do well with papaya. I used GH 3 part bud blood and big bud with orangebud skunk and They seem to do better. If I had the funds I would try all you have suggested just to see. Sounds like your lightyears ahead of me on the nutes and add ons. I know only a few have this answer and I would like to know just what you need and don't need. What packs on the weight more than anything else ???
