NightOwl SSB3 and Q'sB in DWCooler

Welp, ran into some issues with QB the past week :/ Still not sure exactly how they came to be but based on my growing question, potentially a potassium deficiency and maybe light burn. After raising the lights, dimming them a bit, and replacing the res with a more potassium-heavy mix, they seem to be more stable. It was pretty bad, taking over all the leaves directly exposed to light (see pics). Had to defoliate a lot and I'm sure this messed up the bud density during a crucial time. pH was on-point throughout and the ppm was still aligned to how they were drinking, so I guess it's just a lesson learned for next grow. The SSB3, on the other hand, is autopiloting beautifully and fading to a deep, dark purple (almost black). The smell is still intoxicating, so I'm glad I didn't mess that one up. The smell on the QB is hard to pinpoint, but not my favorite (citrus, musk, dirty socks). Hoping I can pull these plants through the finish line! ---- Thanks for following 🤙 Always appreciative of tips or suggestions
