Honey, I Shrunk The Kids

I assume you’re working from clone - because of the staggered nodes. This makes topping tricky. As you can see from your previous topping, when there’s not symmetrical growth, topping doesn’t work as well. It’s a totally different technique when topping clones compared to from seed IMO

Yep, about the right size. Love your super clean and tidy grow space! They seem to be lacking from phosphorous though (not potassium), hence the reddish stems and slight discoloration in the leaves (pic 3). Giving them a P/K booster in addition to their grow nutrients won't hurt them, it will only do good things. I have had many plants with 13 blades on one leaf over the years, 7 is pretty average, 9 is more normal and 11 is quite special. Hope this helps, Organoman.

It will be fine, now that it has dried out and has started healing itself, there is no point trying to stick them back together, which only works if done right after the injury occurring. Keep it dry and there will be no problems, if you cover it with tape/ties etc this can lead to moisture where it shouldn't be and then this can then lead to fungus and/or mould attacking. Best thing is to leave it and keep it dry. I have had plants with split stems 8 inches long and fall into two parts and just left them and they were fine. You can support the branches so the split does not get worse, but now that it has dried out, don't close it up, this is likely to cause more damage than just leaving it be. Hope this helps, Organoman.
