Once you start flowering they will double or triple in height. How tall of a tree do you want?

IME they stop vigorous growth for a few days to a week just before they start their flowering stretch.

can u show us a picky?

hows the drainage?..... also idk if this helps... but i found a fricken ants nest in a pot before all up in my roots.( i figured that was stunting the growth, so repotted with new medium. got my plant back growing but still didnt produce much

the story....
someone??? left a melting twix on the bar in my backyard, and i had left the plant up on the bar from checking it out the night before. next morning, ants all over the bar, traced the source right to the roots. little fuckers!

No answers till I see some Pixs

maybe root bound in the container...?
