I am currently in my 5th week of MG MC 6 month and it is not a bad soil, it just sucks if you are a newbie and over water it like I did... You can only try and get the ph correct and hope the girl recovers. They do have fungus gnats, but they were not that bad and I only see one here or there... using nematodes helps and will be ready for my next grow. The soil was great for vegging as they run 22 N
but anything with long feeding is not good for new growers who might over water the plant. I do not like that I have no control over the grow!!! I have roots organic and FF trio along with a ph pen, a tds pen and way better growing environment. But it was bag seed, so I did not care and I will take the good with the bad... just won't use it again!
