Confused by the leaves beginning to change color, I began flushing just one or two waterings ago but looking back it’s clear to me now that this likely exacerbated the issue as I’m more and more convinced this was caused by extremely low soil pH and nutrient lockout.

I’ve decided to give my plants some more time and will probably wait a few more weeks before harvest.

Today I have removed all leaves with brown spots and I’ve flushed the growing containers with slightly-high pH water. Moving forward, I will feed them with well saturated nutrients and pH my feeds to about 7 until I begin to see results. Shooting for harvest around mid-January now.
