Shot I suggest that you get some perlite from another place, any plant care nursery, places who sell house plants and such, have it. coco peat needs hydro ferts, ph ec and what else, it will be troublesome. get perlite, flush it very well then mix it with good soil, GOOD soil, buy a ready made bag of soil from the same nursery where you find perlite, and not from the retard who doesn't have it. Ask for thge better soil, it will be 2$ more, pay them, you will not regret it
