ive read on some posts that a plant might not bud as quickly if it has a low amount of Nitrogen in its flowering stage. It is important to still give Nitrogen but not excess amounts. I cant really cite this info but maybe this is whats doing it? other things might include proper rooting/transplanting. If a plant hasn't gotten to its full maturity before it flowers it may also take a little longer than normal. Again this is just info i've picked up. Please correct me if im wrong
That actually sounds like a good explanation for my plants.
They have been outside since the middle of May, first showed signs of flower beginning of July, but still have about a month to go on my Indica, and more on my Sativa.
I had zero knowledge of what I was doing, and sprouted them under a 6/18 flour. tube fixture, about 4' up from them, and that is what they had until they went outside. About a month after that was when I decided they weren't going to die like my previous tries, and started reading about them.
By late August, they were very green and healthy, and I stopped giving nitrogen all together.
Last week, I started giving a little nitrogen again along with the regular stuff I give, because they started turning yellow, and within the last week I probably have gotten as much bud growth as I did in the prior 2 weeks.
