I checked the Ph, it's a steady 7.0. the plants were initially in smaller pots with too much fert, i took the plants out and put them in bigger pots with 80% new soil. they got much better but 3 weeks later (which is now) they are beginning to show signs of overfert again (but i haven't fertilized). They were doing fine for 3 weeks and all of a sudden they are showing overfert problems. The soil is not way too wet, i water once every 4 days or so. Anyway, what should i do to fix the problem? If i have both burn and deficiency then how do i add more fert without burning further?
