Red / violet leaves any symptom?

It's the strain, it looks beautiful to me. IMO! Probably start to fade in a week and get even more colors. Drinking will start to slow... Very pretty. 👍

Macro and micro nutrient Deficiencies you need a full bloom fertilizer with mag call after a good flush to remove excess salts that might be causing nutrient lock up

its a phos deficiency she needs more P and K in my opinion though depends how far along you are if your in late flower could just be the plant showing you her colours many do towards the late stages looking pretty :)

How many clones of this plant did you take? If you have 3 or 4 of them and only one looks like this it could need a touch more cal mag but if they all look like it then its genetics. Dos si dos 33 is spose to turn all kinds of amazing colors so dont worry too much. Looks like pretty much every other do si dos strain ive seen.

it's calcium deficiency, did you check you EC of your tap water? If it's less than 300 ppm you might add some CALMAG. Is your pH ok ? During flowering should be a bit higher, from 6.2 to 6.8. Let us know

You have too cold nights or even days, could make a bet that nights fall to 15 and days max 21, otherwise it's genetics. I personally had no deficiency with such look and I think I had all of them ;( All the Best !

It looks like blushing but maybe also something else given the yellowing from the inside out on that fan leaf and deep pink/purple veins. Best to link your diary if there is one. Will help some of the others diagnose this.
