With no nutes going in, this is a mutiple defc. deal going down, but P seems the worst of it,.. This snowballs very quickly, as other nutes interact with each other in how they get taken up and metabolized; short of one or more can kick off others as well,... BTW, most soils simply don't have enough, nor the correct balance of nutes unless it's made to be "water only" types.... even that is debatable that I see; KIS, one of the best, still says to get best results you need to amend after a while especially in bloom,...
Soil pH is KEY, never be ignorant of that or it will bite your ass every time, trust me; nute availability is tightly linked to it... get yourself a good quality soil pH probe like the Accurate 8 (CWP), not one of those cheapo skinny metal probe types... the A8 works the same but is much more robust and better tuned...
Meantime, get feeding ASAP,.. what do you have?
