purple discoloration on CA outdoor clones

Hi i am new to joining this forum but have learned a lot from it already. I have been growing plants outdoor near the Santa Barbara, ca area for 3 years now and have experienced purpling of the stems every time. Every year I do things a little different but this year I am growing blue dream and blue skittles that have been under 16/8 at the nursery before I got them and have since been in the natural sun light at about 13hr 45min for alittle over a week. Temperatures at night are anywhere between 45-60 degrees, they where transplanted to a one gallon pot the day before I got them, I did some heavy trimming, tying down and topping on both plants since I recieved them, watering with ph ranger between 6.0 and 7.8 and have yet to feed them my planned nutes of 1/4 dose ff big bloom/grow big and 2ml cal mag because I don’t want to over feed since I don’t know what the nurseys soil mix is. Could the purpling be from over stressing my clones? I have read forums on this subject before and have not got a definitive answe. Should I feed my nutes? Am I missing something? And help would be appreciated

Here are some examples from this years clones, first 2 are blue dream 3rd one is blue skittles

It can result from a deficiency of either of the 3 main ingredients: nitrogen, phosphorus, or potassium. Plus, the inherent strains genetics and to some extent, cold. I no longer worry about it and don't try to chase down the culprit. I'm in N. Cal, and try to "keep it simple, stupid". Having blueberry in the genes is a telltale sign. Don't overthink, is my advice.

This is nothing worth stressing over.

For the plant, and the grower. Here in the real CA, canada. 90% of plants look like that lol.

Thanks for the advice!

Yeah, practically all my plants turned purple when they finished last fall-winter. I grow a couple of purple strains: GDP and Godfather Purps. But the Cheese and Paris OG plants also got purple AF, especially in the cooler weather with short days.
