Hey, not too long ago I found some useful information in one of the blogs here https://highway420.club/blog/banana-peel-tea-for-cannabis, where it is written about how to make cannabis fertilizer from banana peels, i.e. from food waste. This is a really great alternative to store bought fertilizer and I have already tried it on my pots. In my opinion, the effect is visible after a few days. In general, pay attention to the specified blog, as there is still a lot of interesting things for the grower.
