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?

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! 🙏

Too little calcium in early flower?
I’m in the early weeks of flower and am seeing this happening. I thought it was due to an attempt at foliar feeding, but those initial problem leaves have been trimmed. Is this a calcium deficiency, and if so, how can I address it? (NLS top dress/coconut powder/recharge)

TDS
I’m on week 6 today. Is this a good TDS reading or should it be higher/lower? I have the unit set to 500 ppm . I used 5 ml/gallon of tiger bloom, 2 ml/gallon of bud candy & big bud. I also added 1 tbsp of epsom salt to lower the ph in my soil.
