Look at the tops here. It is cool to watch how the build from this point on, new little leaf tips pop out of the top, gradually grow out then horizontal as the calyxes above then get fat, then it does it again.
Everything from now on will build and stack like that, even the lower buds, but slower. This will cause the lower node flowers to fatten, and if there isn't too much stretch join with the flower above them. You'll see them separate again when it dries.
About even with my thumb is where the top starts, then there are 3 sets of buds that were the lower node flowers.
The longer you can let it go, the taller and fatter each flower gets.
and watch that they don't starve because they'll cycle through some water now too. At this stage, as long as you are still conservative about it, 'drowning' them is not very likely. So let them dry out, but not too much.
