So a week after my last post in this thread, i began a weekly fertilizing program for the first time ever, on Cole's advice, and kept it up consistently every week, until mid May, when i took a break from it.
This specimen had always been a bit finicky in my care, but since keeping this clone watered and well fed, it has resulted in it now looking like this...
Now it still hasn't flowered yet,
but it has been stacking up leaf layers, like a K-tel Patty-Stacker® from the last century.
Olde CP nuts never die - they just recommit themselves...
