At this point I would not worry, plant is almost done, so it's natural for the foliage to start to die

Yellowing leaves
Leaves seem kinda yellow on one hand. The bottom right hand corner one looks like she needs CalMag but I'm not sure. All the photos have been taken under the same light. Used to over dose the nutrients to prevent burn but continually gave them 1mL/L calmag each.

Deficiencies? Brown spots, yellowing and purple stems
What is this deficiency or maybe toxicity and whats the solution? She is fed with biobizz chart instructions but with every other watering. She is big so I'm guessing I should water with nutes every time? She showed this first week into flowering.

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.
