Need some help with my northern lights plant. Its lower leaves are turning very yellow. They were looking a little yellow last week so I flushed it last friday and now those have turned even yellower. When i checked my runoff PH after i flushed it last friday it was about 6.5-7. Ive been giving them Fox farms grow big nutes, but havent fed them in about a week and a half, and then flushed them friday like i said.
you havent fed them yet after the flush? you might want to try a very light dose and see what that does as long as your ph is right you know.
