P/ pH problems at optimum range

Hi,can't figure my password so I made this new account

to make it short: I'm not new to growing, just new to the system. I run a DWC in the veg. and I'm always having P-deficiency (no matter which strain) when I'm running the system woth a pH of 5.8-6.2 which is -according to all the literature -the optimum. I started tried different pHs , now I'm stuck with a pH around 5.0 to have green plants. But I'm still missing the vigor they should have plus I can't explain the problem (which stresses me the most) .

Any suggestions?

first I worked with atami, but at the moment I trying AN sensi grow ph perfect (I know, you should not fix the pH with this one and I didn't but it didn't work out so after a week I started to correct the pH, which works like described, as did atami)

My ph swings from 5-7 and the plants don't seem to mind. I'm always trying different nutes. The Floranova has the most stable ph.

Prof,
Why are you so sure you have a P deficiency?

You should probably be using some myco product to introduce some beneficial bacteria to rootzone. Will help with P absorption. And like Natureboy said...swing is a good thing. It exposes rootzone to a range of ph points.

because plants show p def.symptoms (also micro nutes, but mainly p)
and the swing doesnt do shit for me because i never run into probles with the cationic nutes.
