Topping into flowering.

I topped my plants five days ago, they are vigorous and have nearly a dozen node's each. Could I throw them into flowering tonight and begin to finish them?

Yes, they would be fine but you will have higher yields with longer veg. Many people go from start to finish on 12/12

Well they are four feet tall they were growing crazy for the last two weeks they outgrew me so I topped them, now they each became really bushy they look great. Sorry I don't have a camera.

you should be fine but remember that they will still grow a lot taller in flower and you wont want to top them then
