Currently growing in soil, farm farm ocean forest with a COB light setup.
I'm using Earth Juice Grow, Catalyst, Cal Mag, and PH Up. I started getting random spots of yellow on leaves, hence the Cal Mag.
My water comes in at about 7.5-8 PH.
By the time I mix everything up, I'm at 5.0 PH
Are there other additives I can use that are beneficial to bring the PH Up without using PH Up?
