Next year consider doing what I do. Build a little black out chamber for the plants, and put sexually mature plants out in late February Or early March, let them flower like normal. Once they get a couple weeks in, do light deprivation and harvest in June.
Put next fall crop of sexually mature plants out in June, closer to the solstice the less chance to re vegetate. That way you don't have to deal with reveg and you get dank,dense and yummy buds all summer and there are naturally flowering plants for fall.
The high amount of clouds may have impacted your plants ability to revegetate properly like it needed to, but should still be able to grow dank,dense buds in cloudy weather, it was sexual maturity of the plant as related with the timing, which is inherently linked to the amount of Sun, and darkness. Use mother nature to your advantage instead of fighting her
For your current crop, your potted plants should put out some nice and solid buds. I really hope your in ground ones do, it looks really confused. I think once the days get short enough it will just try to pack on some buds with what it already has. That's why it's not vegetating because the fibers are so woody already, they tried to get ready to put the weight on too early. The reason why Craw mention the pruning is because of mold and airy buds. We don't want a clustered mess of branches that is a breeding ground for blocked airflow, those little things will split up the energy and produce leafier buds, so I try to trim these bottom, revegetated branches to send more energy up to the "Main colas"
In fact, you can see in my journal, I call it the "Big KC-45 in the tent", this is a plant who has been growing since February outdoors, it flowered and then re vegetated, I even harvested a couple grams of really low grade bud off it back in April, I had to prune and trim off all of the revegetative growth down below, now the entire plant looks good as new.
Professional greenhouse growers who use light deprivation see up to 3-4 harvests of buds off the same set of plants per season. They just trim all the really good top flowers off, while leaving those bottom nugs on there, and they just keep growing back all season. They have specialized automated tarp systems though in very controlled outdoor greenhouse environments. My method is much more laidback, I just put my pots in the garage at the same time everyday, and take them out at the same time.
My latitude is 34 degrees, I'm thinking as you get closer to the equator there are more reveg problems, Craw probably can input on this and ask his peeps out in HI, from what I've heard there can be some crazy reveg problems in HI, still trying to figure it out. Region definitely effects the timing heavily.
