Errr... what are you planning on using the Nitric Acid (HNO3) for? Acidifying water for an Acid/Base extraction? Please don't put HNO3 directly onto plant or fungus material. If you would like to do an acid/base extraction, put some HNO3 (or acetic acid CH3COOH, or hydrochloric acid HCl) into water and use that to extract the plant or fungus material. Then base that material up with NaOH, or Ca(OH)2, or NaHCO3, or Na2CO3.
FYI, most people who speak English aren't going to know what "Kalium" is. The English term is Potassium, so you have some potassium nitrate tablets. I'm not sure what someone would use KNO3 for in the process of obtaining and using psychedelics.
You ought to post an introduction in the relevant forum section so people can get to know you. Welcome to the Nexus!
