Hey Growmie, You are definitely right this is going to be a phosphorus deficiency, to fix this issue flush your plant with clean, pH’d water that contains nutrients that includes phosphorus, for your regiment it seems your Bio PK 5-8 is your source of phosphorus. This will also remove any nutrient salts that may be affecting the uptake of phosphorus and help restore pH to the proper levels.

Potassium deficiency. Increase your Bio P/K or the "Green Sensation" slightly and possibly remove some other similar fertilizers. Giving your plants a few things in the correct quantities is far more effective than giving them a little bit of many things.

Grey leaf tips Booth plants are showing some kinds of burn and I am not sure if it is nutrient burn or light burn or if there is something missing. Looks a bit like MG deficite but shouldn't the plant take that from the soil in that state and age?

Strange discoloration The plant is becoming less green, more yellow, dark green/blue, and the tip seems necrotic. She received a little more light intensity (TS1000 at 50cm, 25%dim to 50%dim) when she was repotted on the final DWC. T.A. (Growing on FeedChart) was used to create the nutrient solution.
