You should have plenty available potash at that usage rate so the issue has to be some stress on the roots limiting availability. Nitrogen and potassium are needed by the plant in the highest ratios so any initial lockout symptoms tend to show with either of those two elements. Potash lockout is more common with under-watering than over. Did you let it get a bit too dry lately? I see some plants get upset like this from under-watering.
I’m positive there is enough potassium releasing and is not pH related as potassium has a wide pH range (5-10). Something is stressing the roots out and I really hope it’s not the worst case scenario, root pests. Do some investigating.
Ok you’ve got me thinking I had this plant on a bottom feed wicking pot and removed it from it a few days before these symptoms showed up because I had to move the tent some roots were attached to the wicking lines could that have caused this
