After flushing multiple times, and checking the ppm of the removed water, I realized how much nutrient build up I was subjecting the plant to. Big lesson learned that I need to add ph’d water without nutrients more often and check the ppm after I mix it back in.
Leaves are starting to lighten up from dark green and I noticed very slight deficiency on one or two leaves. Now I’m at 25% nutrient strength and it is starting to grow noticeably faster.
