Thanks for the salve recipe. I cannot get pure alcohol in my state--the best I can do is 151, but I do use good trim and small popcorn bud rather than already vaped bud, so does have more cannabinoids initially.
I would suggest that think about growing organic. In some ways it is the easiest way to grow because unless the pH of your water is way out of whack, you do not need to worry about pH. I am currently using the General Hydroponics line of nutrients, called General Organics. You can buy a "GO Box" that contains all the nutrients for a number of plants from start to finish for $40. In addition, if you do run out of nutrients or decide that you do not want to buy premade nutes, you can make organic teas for feed. You could repot in an organic soil, removing as much of the MG soil as possible.
This is a hobby that is going to take a certain investment of time, money, knowledge, and love. It is about a 4 month process from planting a seed to smokable bud and there are numerous pitfalls all along the way. You need a well set up dedicated grow space and adequate lighting. Those fluoros are not going to be adequate for much longer.
