i 3rd that motion but make sure your ph is in check before adding more p in case its out of wack most of the time when seeing a DEF is make sure ph is in check before chasing the problem

this is new growers biggest problem when they here Deficient they just add more. incorrect most of time. check ph and run off it will be your best friend and worth it to get a nice ph reader

You didn't list enough information for a real answer there is 90 million ways to get a leaf to be Phosphorus deficient. Also I believe I see pH fluctuations so I think it likely is under feeding coupled with slamming your pH back within range after the associated pH drift. But we would need to discuss what you're feeding them and why, decide what ratio to come back at her with.
