General health and CalMag advice
Reduced watering to 850 ml and seems to want this every 24- 36 hours. Plant seems to have perked up however still have yellow leaves / brown spots. I’m feeding 0.5 ml calmag per litre , should I continue this? Should I be worried about the state of the plant.

Leaf Spots, weak color, and leaf ripple
Please help me identify possible causes of this: small spots on leaves, minor color fade (not burn) along edges, and strange 'ripple' effect. A user commented that he thought my plants looked deficient but hasn't elaborated further yet. What might this be? Multiple issues?

What have I done wrong and right?
I'd love some critical looks at my plants, there are two in this grow. With only a few weeks left, I don't think there is much I can do to really improve things. But, please look at my pictures and tell me what you see wrong and what I should have caught. THANKS! 🙏

P deficiency (95% sure) help request.
P deficiency. I cannot measure soil PH but it's "Biobizz Light Mix" and I use suggested BioBizz nutrients. Now is cool here and the temp range is around 17-13 °C. There's a method to fix the issue? Should I heat the box?
