With ocean forest you probably have around 3-4 weeks before the neuts in the soil run out, I used fox farm I didn’t feed any neuts until mid week 4 and started at 1/4 recommended doses, went to half recommended after about week 6, and continued that till I was about 2 weeks out from finishing
Pretty sure ocean forest has enough neuts for about the same amount of time, but I’ll let other make that final recommendation as I only have a single full grow under my belt lol
Here’s my first grow journal if you wanna read through it, my new journal I linked above
