do you spray your plants? foliar feed?

I believe you have a ph lockout, magnesium, calcium & more
no matter whats locked out its why.

complete a soil runoff PH test.......
with PH corrected water (6.5-6.8PH ) pour enough water in the pots so the water runs out the bottom of the pot ...collect & test the PH of this runoff water....post both the watering going in the pots and the runoff ph
