That's what I thought, at least what I thought I thought I've used it as an additive in oyster mushroom cultivation.

black strap molasses.
BUT don't use it for it's nutrient content.
Only use it for AACTs
Neem is awesome, has sulfur too, and sulfur is a commonly overlooked nutrient.
Between neem meal and kelp meal, those two have the best all around mix of stuff for your plants.
