I have a soil question. I used Fox Farm Ocean Forest (OF as I’ve commonly seen it abbreviated) for the first grow and plan to use it for the upcoming grow. I have a full bag leftover that I bought last year. It’s date stamped 6/something/21. It’s been sitting in my carport since I bought it last year. Question is; should I treat it like a new bag and not feed for the first three weeks? Or have the nutrients been depleted from being exposes to all the temperature and humidity changes over the past year? Thanks in advance for any help.
