Kind of a noob myself but it appears I ran into the same issue a couple days ago using ffof. The advice I was given was to pick up some dolomite lime and mix with soil when I transplant.
I agree with Blindandslow. Our two plants were looking really sad. Yellowish new growth, chlorotic leaves with necrotic holes. I started dosing them with the recommended amount of GO Cal-Mag+ just about every time I watered for the next few weeks.
