Having got back my water test to diagnose the previous deficiency, I have corrected by adding superphosphate to what I calculate to be 30ppm (tho it's in the beds so should be slow releasing), a small dose of magnesium sulfate, and sone iron chelate, and a pinch or borax.
while the other plants look to be grateful, my bok choy doesn't look so happy and has rapidly developed what I guess I would describe as intervienial necrosis?
At first I thought it was slugs rasping on the surface as the tissues were thin in many places, but today when I came out it looks to have developed into full on necrosis.
Any info on what this might be, what I have done wrong, and or how to remedy would be much appreciated.
