Obviously cannabis is not on official but many community servers on xbox do use it.

At the moment the plants growth rate is very sporadic. You can water a seed and it instantly is at full size but dead. Other times it goes through its 3-4 growth stages within 20 seconds. Other times it takes a few minutes.

I would suggest making it take a similar amount of time to other plants. I think thats 30 mins or more now? Or if shorter (which is nice haha) maybe at least 5 minutes so you have a chance of saving it if it's diseased.
