Amnesia Auto Aquaponics

Well Ive been combating this Phosphorus deficiency for the last week or more. Had to tap into synthetic nutes to keep her going. Only using the Beastie Bloomz for watering from above, dont want to hurt my fishy friends. Been using peat moss inside my fish filter to help regulate ph at a lower level. Wouldnt want it to drop much more for the fish's sake so have been adding just plain RO water to the tank itself with a ph of 7.5. Pruned out some unnecessary tags, resulting in noticable flower growth. Probably getting to the "fattening" stage, hard to judge by just number of weeks with autos. This one was planted about 3 weeks after my Dark Devil Autos and Devil Cream sprouted, those still arent showing any flowers yet, while Amnesia here is almost finished. No Superthrive was given to Amnesia at any point in its life at all. The others were dosed up until about 5 weeks in. Have to research what food types for my fish produce more phosphorus or if theres some nitrifying bacteria online, our Wal-Mart no longer carries any so I used microbes I had in small amounts in the tank. Any comments with thoughts on this would be greatly appreciated! Thank you, best of luck to all.
