Biobizz: When to start nutes and bloom when growing?

I hope all is well with you all

(Currently using foxfarms ocean soil, just in case you guys need to know)

Wondering when should I start using the nutes?

I was looking at South Korea's grow, and he was using the nutes and bloom simultaneously during flowering?

I guess I'm asking, whens the best time to use the nutes & bloom?

Someone please help make some sense for me

thanks for reading!!

how many times a day do you nute/bloom though?
