yeah I checked it...it was actually sittinr right at 7. and I thought it looked like either calcium or potassium like I said before. I have some cal mag that I bought a few days ago that I can use to foliar feed. would it be ok to foliar feed today even though I fed them ferts 2 days ago? and one of my other plants has the same shit happening to it. what can I use for potassium? or will calmag do the trick? I don't know if the tiger bloom I used has potassium in it
