Hey BB, slight Nitrogen toxicity? You are correct, but it is minor. Tent environment is solid as well. I can copy/paste some instructions on how to balance out your nitrogen without starving your plants. I'll drop you a line. And even though I've seen your pics before I also notice they have been stretching a bit. Strong stems and laterals but long internode spacing.
I'll give you some info in PM and see if that helps at all. Cheers a good luck BB. Every little thing, gonna be alright.😉
