Purple Leaves (not purple bunds!)
Noticed some purple patches forming. Im sure this happens every grow and I end up with a range of answers, but as I'm using some utes this time, I wondered if its more likely to be one answer over another this time. Think its phosphorous deficiency?

Why is the new growth turning purple?
Is a night time temp of 15degrees the cause? I can't keep it up without making it too hot, or could this just be a phosphorus def.? I fed her well yesterday and yet to see any difference, as far as I can see this isn't typical for the strain

Purple leaves getting worse!?
So I started getting light purple/yellowing last week, after my last grow question, I landed on potassium deficiency. I gave a healthy dose (2 tbsp in a half gallon of spring water) of Fox farms big bloom (0-.05-.07), within the last 48 hrs and the purple looks worse? Any ideas?

Starting to fade? Or nutrient deficiency?
One of my plants has several fan leaves that are turning yellow/purple, and I can't tell if it's low on N or starting to fade. The plants are 2 days into week 5 of flower with a 9-10 week flower period, so it seems a little early for it to be turning colors like this.

Two problems in a week. I diagnosed the first one based on similar grow questions (: maybe not right )
First three photos appeared a week ago, I decided that it is calcium and took a more reliable Ph meter, maybe not right, but no new spots appeared. Second problem at the end of the week, 3 days after defoliation 2 large lower leaves and 2 leaves inside. 30 hours after watering.
