splitting and hollow stems?

[psilocybin warrior]

ok so on alot of my B+ the stems are twisting, splitting, and hollow does anyone know a reason for this?

To me twisting is a cool thing for some strange reason.
I'd have to say that some of them just like to do it,
also if you rotate your trays or cakes around in your FC they will have a tendency to twist also.
I have had splitting caps as well as stems.
I would have to attribute splitting of stems and or caps to a few things.

1. Vigorous growth.
2. RH issues,which may not always be the case.But extremes in RH drop and raise can attribute to splitting.
3. Mold and or Bacteria on the fruit.

I've noticed that hollow stems can be caused by No.2 in the list above, along with many other factors,such as "Luck of the draw" due to multispore innoculation.
I have had Cambo's that have had hollow stems and some that have had solid stems all in the same tray,which I have no explanation for 
A more expeirenced grower may be able to be more detailed in explaining this interesting phenomenon.
Hope that helps P.W
