The purple is indicative of a phosphorus deficiency, especially in flower when the plant needs a good amount of it to build buds. The purple could also be caused by cold temps though. If ur temps aren’t dropping below 65F this is probably not the cause and I would lean towards a phosphorus deficiency. It could be genetic trait too. I would check the temps, if those are fine then slightly raise the amount of phosphorus your feeding her then be on the watch to see how she reacts.

My temps do consistently drop just about every night to 64° when lights are off, my rh hangs around 40-50%, with lights on my temps are 75-80. but I planted the seed in a soil mix that's 1/3 promix, 1/3coco loco, 1/3 castings amended with dr.e468 and gg284, lil kelp and alfalfa as well. I did top dressed 284 and castings when it started to preflower like a month ago or so and last week I did feed her a EWC tea with seabird guano and molasses and a lil bit of 468. Other than that tho in 56days mainly been just water. it's actually purpled more since the tea..

I would still lean towards her being hungry. Using the pics and ur info about Being 57 days since sprout and a month since she started flowering she still has a good bit of growing/swelling to do before harvest. The colder temps at night don’t help. colder temps make it harder for the plant to absorb phosphorus. This means there is a lack of Chlorophyll being produced resulting in the purple shade you are seeing.I can see there is also some yellowing in the leaves which is okay in flower but it also tells me she’s probably hungry. Try and get those temps up a bit at night first if you can. if that helps great, if not increase nutes slowly

Yea I just got an ac for my space around the tent bc my temps were getting high during the day 90-93°f. The plants didn't show heat stress bc I think I have decent air exchange and my humidity stayed higher but I still didn't like it.. Ive been using the ac for 13days tho. I'll start turning the it off at lights out.. I just looked at my thermostat and it got down to 63°f last night smh.. I have other flowering plants on day 27 flower and one is showing purple as well..

They look good! Like I said some strains just adopt a purple hue genetically and that’s just how they are supposed to be, but with the temps being where they are at night I think that’s where you should start.
