Which notes do you guys use and what is your experiences doing it.

I personally follow a less is more mentality with supplements as a general rule. It's my firm belief that most deficiencies diagnosed are more lockouts from being " loved to death ". Beyond my pH down and Flora Trio, I just use Kool Bloom booster in flower. I dabbled with a flushing solution once but can't say whether it really worked better than just water. I get the mentality and pushing our strains to their limits can be rewarding, I just shoot for convenience and cost effectiveness in the end.

I love to make my own compost. With some of my kitchen waste. Cabbage is one of the best things to compost for cannabis. Materials I compost are cabbage,spinach.crushed egg shells.leaves around my area and Dandelion greens they're also a good source of calcium, iron, potassium, and zinc, plus B vitamins and vitamins A, C, and D. When it's composted I mix it with promix hp. Best of luck on your grows.
