Medium - 75% Perlite 25% Vermiculite

RH - 50% to 55%

My lower leaves are color changing and the stalks are turning purple. is it nutrient deficiencies or excess?
From what I have researched it looks like a deficiency of phosphorus or potassium but I am not sure at all.

I would love for some help

This is normal for fan leaves during flowering. The nutrients are being sucked out of the old leaves to help grow the flowers. Leave them till they wither then remove. There might be a slight magnesium deficiency due to pH of water but looks OK

I see you adjust to pH 6.5. I would lower that to 6-6.2. I try to run my hydro system at 5.8, but soil should be a bit higher. You may need more cal mag since you are almost hydroponic with your mixture and no natural hardness ions. Try running pH 6.0 nutrients and water in the future with more cal mag
