Starving for phosphorous and potassium. Add a P/K booster to your feeding line up, or increase the dosage if you are already using one.

Looks like your soil ph is out of line. You need to test run off and yes looks like it was getting too dry at least once. Water is heavy. Can also Guage Potter moisture by picking them up. There will be a big difference between wet, and dry weights. If in soil you should be running a wet and dry cycle. If in coco it is totally different.

Too Much Light?Top looks yellowish, more so IRL than in the pic and the new growth is kinda taco-ing. Just under 24" from the light, 78F and using Photone the DLI was at ~30. I don't really trust that app but if it's even sorta accurate, 30 might be high with no CO2? says their charts anyways.

Yellowing Leaves? Nutrient deficiency? Fixable?Is this a nutrient deficiency? I'm 3 weeks into flowering. 2 or 3 weeks away from harvest. I'm using Biobizz Grow, Bloom and Top Max. Is it an issue that can be fixed? Or do I just need to get it right next time?

Nute Burn? Or something else?I'm seeing a lot of yellowing and dead/curling leaves on my girls. I thought it was nute burn so my last 3 waterings were nute-free, CalMag Only and pH'd. It seems to be getting worse. Could this be something else? Any advice is greatly appreciated
