Is this phosphorus deficiency?

Hi there, new to this forum and in need of some help with my growing babies.
Yesterday i came home after being away for three days and one of my white widows in the veg room didn't look too healthy. The newer growth seems to be fine but as you can see in the pictures something is off. I did check the stems, some show a purple hue and some appear quite "flimsy" with not much vigor.

Info:
White widow
Grown in bottomfed autopots (15L pots)
Soil/perlite
Reservoir pH @ 6.3 (it varies between 6 - 7)
Nutes are canna terra vega, ppm at approx 420. no pun.
additional cal / mag added due to having some calcium issues on all my plants before.
Temps ranges 24c / 19c, RH 65%
900w LED (400 actual)

only one out of 3 is affected by this at the moment, all share same reservoir.

After some researching i think it's phosophorus deficiency, could i be wrong on this? Could it still be a calcium deficit? I flushed her yesterday with pH'd water and put her back into the system.

Hey it looks like K deficiency with the ph being too high, get the ph down to 5.8.
