Re Veg

I want to re-veg my plant when I have harvested (so that I can take clones). I was surprised to see that flowers have formed all the way down to the bottom of the plant (tiny ones on the smallest shoots) will that make a difference to its ability to re-veg - I understand that I can't clone whilst it flowers - what should I do?

you can reveg, itll only grow slow and strange at first but eventually itll grow like normal.
Here is one of my threads where i cloned a male plant way into flowering. You can see how some of the leaf tips are very long and before this stage it looked even stranger. Give it some time and the next few nodes should grow normally (i suppose).

interesting was also that because it had male preflowers on the tip, the top didnt keep growing normal after reveging, but rather had the same effect as topping the plant. 2 new nodes grew out if you can tell in the picture, maybe it was even 3.
