Why do you think the purpling is phosphorous?The symptoms you describe are sounding like general base nutrients are needed. Too much nitrogen will start to lock out nutes also. Well too much of anything causes conflicts.
The dark green leaves if low can be potassium. Especially if the leaves are dark and thickening and droopy at the tips. Also the white tips have relation to magnesium and potassium.
The purpling is probably phosphorous. I would add a balanced general complete Grow nute with a good amount of runoff to basically re-set the medium. Maybe a 25% or a third strength to start.
Every time I've had purple leaf stems, adding mag and/or correcting PH fixed it.
Ideal PH range for mag absorption is 6.0 - 7.0 for soil.
6.0 - 6.5 is best for hydro.
