Also i add ZERO extra nutes due to it being a super soil. I ph my water between 6.3-6.8 but that is it. Its been amazing up until now.
Yes, and the overall lime greenish color compared to my other plant.
I wouldn’t worry about the isolated area in the highlighted area. It is most likely genetic and is perfectly normal. We all experience that here and there.
The difference in tones probably is so as well, though you might have slightly less nitrogen available to the the lighter one. It really isn’t enough to worry about at all.
You’ve said super soil, which can encompass a lot of things. It may be time to start introducing nutes. Do you measure PPMs? What, specifically, is your super soil?
I really don’t think you have much to worry about.
