Hello!

I just ordered some Neem Seed meal. I plan to use 1 cup per cubic foot of soil. Is this stuff an N source, or pest prevention, or both?

I've also seen cotton seed meal around. In the past I've read that you shouldn't use this stuff because cotton is treated with many pesticides as a plant. Now it seems like people prefer cotton seed meal to blood meal as a nitrogen source. Has something changed in the way cotton seed meal is produced, or is it "a lesser of 2 evils" situation?

If I use seed meals in nutrient teas will I get extra hormones/auxins or something special because they are seeds?

What about Sul-Po-Mag or Langbeinite? 0-0-22, with magnesium and sulfur. Some people say this stuff is great, others say this much water soluble magnesium with cause lock out issues. Does anyone use it? Should I grab some gypsum instead?

Neem seed meal is both an N source and IPM. If you're looking for another source of N I'd opt for alfalfa meal over the cotton seed meal

I already use the alfalfa, I was just looking for a little more nitrogen. I thought the seed meal might breakdown or release slower.

Maybe some fish meal?

You could use a variety of extremely good stuff there, crab meal is around 4% nitrogen.
insect frass is lower but great stuff
rabbit manure is great stuff, so is alpaca manure
cottonseed meal is for plants that like more acidic conditions, I use it for my blueberries. NOT for cannabis, especially if you utilize peat.
fish meal has some N in it.
Usually nitrogen is covered by the crab meal, and neem meal.
I also have a new thing I've been using and so far my plants love it and it's mashed insects, in the chicken feed area of feed stores they sell lil plastic buckets full of dead crickets and mealworms, that's like a mass amount of chitin in there, not too mention probably a good amount of nitrogen.
The only seedmeal you want is neem.
