That to me is your plant isn't getting enough phosphorus. Bump bloom nutes up just slightly. But if it was me I would flush with plain pH water before raising. That way you can eliminate any salt build up and old nutrients and replace with fresh

Get an EC/PPM meter. Hard to say with no feeding strength data. Yellow leaves (chlorosis) with rust spots in the bottom leaves is potassium deficiency, which is normal in flower stage. You might be getting burnt tips because the soil might be too prefertilized with nitrogen. I would stop the veg nute and focus on the bloom for now.

Deficiency?? Excess? Neither?Grown this strain before and had the same issue.. not sure if its a CalMag deficiency entirely. pH has remained at 6.0-6.5 or so in soil and didnt show signs until recently, seemed to have worsened after just two days of only CalMag and Ro water so I bumped up the bloom nutes.3 years ago
