Are the new shoots as thick as the earlier Spring shoots?

Are they otherwise healthy looking?

they are generally thicker or the same, I've read on another post that juvenile bamboo can abort shoots if they lack sufficient energy.
not sure if thats the case cause it seems like the tips brown out so vertical growth is halted but energy than is diverted to branching

Interesting. Can you post a picture?

I've never had any bamboo abort shoots from lack of energy/food that I know of. I have had some die from too much or too little water during new shoot growth. Too much water will kill of most if not all, new shoots if it is persistent and lengthy, and also, severe drought will cause them to die.

The bamboo grove or clump, should normally be producing food constantly, in addition to using stored food for new growth, so it is strange that the new shoots are stopping before they reach their mature height, and then leafing out.

Maybe there is some kind of damage to the new shoots which is stopping their growth?
