It's going to be impossible to tell what's going on if you keep changing the variables every 3 days.
Water, don't water, add nutes, flush, top dress, move the pot, .... I got dizzy just looking at the thread, it was opened on Feb 1 it is only Feb 10 and you've
1) Flushed
2) Added nutes
3) flushed again
4) top dressed
5) readjusted PH
I think you might water a little too often and maybe your soil is too 'dead' meaning it could use a larger culture of beneficial bacteria.
A touch of molasses in a watering, add a touch of worm humus or guano to the next watering. A TOUCH. Just to dirty the water a bit. Maybe 1-2ML per Litre.... that'll put you in the 60-100ppm range of nute content, but the real kicker is the beneficial bacteria that'll travel into the soil along with the water....
FFOF is 'organic' but that label has been so bastardized i would not be surprised there's some chemical stuff in there that passes organic because of some shit technicality - and maybe you don't have the bacteria colony you want and a phosphorus deficiency is how it is expressing itself....
