Great, that is actually even therapeutic to take care of them, best thing you can do if you are able to it. About being afraid of the difficulty of it, look, you are a woman, you are wired by nature to generate and give life and then raise this kid to it's best so it can impact society in a positive way, so growing plants should be a piece of cake ;)

Just remember plant food is light, so no need to go really crazy on the fertilizers, plus every plant feeds different. I am sure your have that cousin who eats everything from the table on family dinners and that one that never finishes his plate :) Of course if you can go full organic then even better, there are recipes online for organic super soil specific for Cannabis needs, just you need to mix and let it "cook" under the sun for some weeks before you can use it. Thi way the soil will be a completely separate living entity from the plant with all the microbial life in there, so it will work in synergy with the plant, thus all you gotta do is give good clean water, no nutrients mixing. Cannabis works in many ways like humans if you observe well various different aspects of the plant from reproduction to how it develops.

When you start growing, if you have the space, I would advise going with 1 bigger plant rather than several small ones. And also I would suggest you have at least 2 different strains on hand, because if you consume it regularly tolerance will go up and it will be good to have another strain(s) to rotate. I am sure when that strain isn't hitting anymore the same way it used to be, the last thing you want to do while growing your own is to have to go and buy something just cause you need different. Plus it's always a good idea to have an Indica and a Sativa on hands, imagine you have important stuff to do during the day and u got only a couchlocking indica or it's 3 in the morning, you can't fall asleep and all you have around is a sativa. All the best, medicate!
