Nothing to be concerned. As you know, there is no set rule in indoor gardening on how long to vegetate your plants. It's up to the grower to decide, based on the techniques of growing, of the space you have, the genetics etc. There are people starting the plants 12/12 from seed, or others doing experiments and keeping them in vegi for 12 months+.
It can be sufficient or it can go more, it's up to you and your schedule. But if you decide to flower them now, they should be great anyways
