Is this 100 day old Jack Herer doing good?

A question from a fellow grower:

This is a 100day old Jack Herrer. It has been stretching with flowers that keep popping up but not clustering. I am using your budding nutes. It doesn’t look normal to me. Should I just be patient or is this unusual.

Looks fine. Hard to believe that it is 100 days old and not bigger.
