The soil should be enough for now. miracle grow is hard on plants some times.
MG soil has nutes in it, usually it's enough for veg a few weeks..
Sooner or later you'll have to buy more nutes. Depending on how serious you are, you can get some miracle grow formula, it won't be optimal, but it will work, give them less than the box says. Like start with half strength.
Or you can get the real stuff, where in canada are you? I'm in BC, and here hydro stores are everywhere. Look one up at yellowpages.ca go visit one, and buy some general hydroponics nutes. I prefer the Flora series.. If you live in Canada like you say, as I do, It's no secret he knows what you're there for, he most likely won't ask you what you're growing, as he thinks already knows.. If he does, just tell him you're growing hydroponic strawberries, they are very closely related to cannabis.
Or, just read some threads around here.. There is more than enough info on this site alone to become a master.. And as always, feel free to ask questions, most people here want to help.
Welcome to RIU BTW..
