Just started a job

in the cannabis field and I know enough about marijuana as a whole but this is is my first time growing it and things like that. my introduction so far has been very nice but I'm wondering if there's any tricks or tips you guys can let me know when it comes to say trimming, feeding, watering, just anything in general you'd want a rookie in the industry to know so you don't have to show it to them. So far I really like my job and it hasn't been overwhelming but it's clear I have a lot to learn.
