Those look really good. Especially the one you topped. Looks perfect. I topped about 10-12 and they are all looking like that. We gave them about 2weeks then we topped the tops

Now some of them will have around 8 new shoots. Its so fucking cool. Im not to sure about the FIM'ing, i guess ill have to wait til the end. It kinda makes your plants look like palm trees

They have this big bushy growth at the top and the rest looks normal. Its funny. Oh, but whats up with that red stem on the last pic? Thats a sign of some kind of defiency or something. I cant remember which one right now. Check out

Now i know that purple stems can be good genetics or reaction to temp drop but red stems are not a good sign. Your plant is doing very well indeed, you might want to check out that red stem though.
