I have not checked the PPM. I did notice that my leaves have little specs of gold on the leaves. I'm guessing the Foxfarm Happy Frog was a little hot for this genetic. So I transplanted them to bigger containers. I added more perlite, a little Gymsum and some peat to my soil. I transplanted my plants at different days because I got busy. I have 1 plant that is smaller then the others because of that.
hi there Ozarks, yeah the lights are actually fine, you can tell because the plants are not stretching badly. It feels too close, but actually it's totally fine. Hope this helps ! 🚀
