weighted average of 4 - 6.5 - 3.5
Maybe, P locking out K.... feel pretty confident about it, but diagnosing based on visible symptoms is more of a guess than a guarantee. Got the burnt to shit tips from P-tox and then damage around serated tips like a k-deficiency. With that ratio, if your N and K are where they need to be, then P will be high. OR, if P is good then n and k are likely low... so best fit with these symptoms is that P is too high.
those weird nutes might have some sort of slow release or this or that... more unknowns with "organic" magic and stuff like that. more steps before it's plant-available, more complications to consider...
