I have some outdoor plants (females) starting to show their white hairs even though the true 12/12 cycle is 3-4 weeks away. Do I change over the nutrient blends from Veg to Bloom now?

This is a matter of choice. you can probably go ahead and make the transition. you could also go another week.
The plant is going into bloom because the days are getting shorter. You are there. Best to judge for yourself. Wither way will work; I am sure. hope this helps. lw

Depending on the strain, it doesn’t need to be a full 12 hours of darkness to start to flower, some will start to flower with as little as 11 or maybe even 10 hours of darkness outdoors, especially with other factors also contributing to the plant’s changes in hormones telling it to flower, like getting cooler and the gradual longer and longer night every day.
It is a matter of choice, as Latewood said, some people do like to keep the nitrogen a little higher for the first couple weeks of flower as the plant is still growing a lot of vegetative growth for that first couple of weeks. A lot of people will do a gradual transition from the grow NPK ratio to the flower NPK ratio, say 3/4 grow mixed water and 1/4 bloom mixed water this first week or two, then 2/3 grow and 1/3 bloom the next week, then 1/3 grow and 2/3 bloom the third week, and finally 1/4 grow with 3/4 bloom the 4th week and then 100% bloom by the time you’ve hit the full 12 hours of darkness.

Does this mean the the 63 day flower period still will not start until the true 22/12 starts? The reason for asking is November can bring in the frost on some years.

Nope, not necessarily, keep an eye on the trichomes.

Thank guys. I knew I should make changes but wasn’t sure how to make the transition. Advanced nutrients has 3 bloom recipes in the Connoisseur line plus additives. They are for bloom weeks 1-2, 3-4 and 5-6. Increasing concentrations throughout will extend the bloom phase nicely.
Can’t wait to switch to Either Flora or Dutch Master for going hydro. Any other recommendations? My stockpile of Advanced Nutrient is well stocked so will save in for soil which is working fine but too much work.

What I’ve stated is a real loose guide “to be taken with a grain of salt”, so to speak. It should be used as a reference in how it makes sense for your nutrients and the schedule recommended for said nutrients and other variables for your specific situation. I’m sure you are already familiar with some strains having shorter or longer bloom lengths, that can also be variable depending on how big the plant is when it is flowered, so I would have to assume the 1-2,3-4, and 5-6 weeks schedule might need to be adjusted or toyed with depending on the strain, just food for thought. But do try to follow the recommended directions that come with your nutrient line as closely as possible as they apply to your situation, the guys that made the stuff probably do know the best ways to apply their nutrients.
