Yes u are right to much experimenting.. thanks bro for replyA worm bin would eat it up maybe? But I wouldn't give it to your plants.
Thanks i go to use it one time per two weeks mixed with water I write the results here when the grow is finishedAmino acids can be used but I don't think straight protein would be of any help. Besides, hemp protein is very costly so why throw it away? What you want is hydrolyzed protein, from a cheap source. I don't know exactly how helpful it would be but I know that some nutrient brands, like Advanced, add amino acids so I assume they have some benefit.
