Once a mobile element N~P~K is locked up in a plant do to pH, are you fucked for good? By changing the pH into the right "range" do you "Un-Lock" those elements again?
If your ph is fucked, just flush it or give it some dolomite lime, or ph up/down. If you flush enough, your soils ph will balance and then you can give it more nutes.
Really can't use pH UP, already had added some Mayan Microzyme and that would have been for nothing! I did add lime but had no Dolomite so I had to use "Garden Lime"... Flushed the shit out the soil and now I have to be patient no way in hell I can water again no matter what the problem is. They are drenched. So your answer I guess Pureblood89 was yes? Yes a plant can be unlocked from nute lockup? I guess either way there is always foliar feeding or last case scenario taking cuttings! lol
