Well congratulations on all your projects, I started up about the same time frame as you. My plants are just starting to improve as my PH levels began to drop from 8.2 to 8.0. From what I've been told / read and what I'm seeing on my set up as your systems cycles in the PH level will fix it self, just give it time.
