Ok I think I have this narrowed down to a Magnesium def. here a few pics of the worst one and new leaves off the bottom of the plant. I know my run off is at 6.4 I’m in promix premium soil and am about 2 days away from transplanting into 5 gallon pots using promix HP with mycorrhizae. What should I do with these? They are mainly healthy and I know transplanting will also help with this.
those leaves are mag the one on the plant is potassium.
Research microbes, humic acid, watch that video above.
Run off ph doesnt mean anything, microbes regulate the ph at the root surface. Your rum off is 6.4 did you water in at 6.5, you should of. Anyways its 6.4 now what? Nothing, its a useless number.
The plant wants its ph where it wants it and you messing with it is messing with the plant.
