So, maybe it’s lockout, or a nutrient toxicity or deficiency. Maybe is from some sort of foliar spray, or an environmental stress factor. I’ve seen a lot so I’m curious as to why I can’t exactly figure it out. If it’s a nutrient issue, which one? Why is it only happening exclusively to a few tables on one specific strain that normally never has any issues. All the other 14 tables look fine, all are off the same feed and environment. My first guess is something either from the coolfog machine, or something bad in the line of the dram when spraying for IPM. Also a nutrient issue doesn’t make sense. Soil EC and pH are good. Is it some kind of pest or pathogen? Anyways here are the pictures. If you can’t see the pictures- uneven splotches on the leaflet margins. Appearing pale then necrotic.

It looks somewhat like potassium deficiency, but not quite. Irregular shapes like that make me think it's something biological. Otherwise, IDK.
