You can grow in MG OBVIOUSLY ^^^
Ppl just hate on it becuase of it's company history or whatev but I could care less.
You're growing for yourself and just wanna succeed I guess.
So I think your answer is yes you can do it BUT if you wanna make it easier for yourself, get Fox Farm Ocean Forest.
It's ready to use out of the bag and FULL of stuff cannabis likes.
Well worth the couple extra $$ spent IMO. My grow has been ALL GREEN thanks to Ocean Forest.
I added some extra organic amendments to it but thats your call.
The better the soil, the easier the grow.
Start with a good soil.
That Miracle Grow should be perfect for your seedlings, but you shoulda transplant into FFOF between weeks 2/3.
Good luck with grow.
I tanked in Miracle grow once but I added shit too in unexact amounts which only added to the headache.
But I've learned so much since then it's crazy, so I think I'd win in a round 2 vs. MG
