i used to use mg and it will kill ur plant the 3 month or 6 month soil will cause lock out from salt build up i know that first hand mg organic and moister controll are fine for growing weed though
This is not my opinion, its what research shows.
There is good reasons why the cheaper soil mixes are often very bad for MJ. That reason is also one that most soil mixes will have. Most people do not research PEAT or PERLITE because it is universally accepted as a growing medium. Many of the cheap mixes are 75 to 80% peat with perlite.
Acidic Qualities
· As peat moss decomposes, it keeps the soil's pH acidic. It is important to not allow peat moss to touch the plant. Burning can occur when the mulch directly contacts plant material. Also, non-acid loving plants' root systems are at risk of burning or suffering from soil toxicity when peat moss is used as mulch. Acidic soil makes aluminum in the soil too soluble for plants, which causes short, swollen roots, according to the University of Hawaii at Manoa.

Perlite, a common additive in potting mixes also contains modest levels of fluoride, .... This explains why the symptoms are seen more on potted plants than in the ground.
Fluoride is added to tap water in almost all major cities.
Other studies have concluded that fluoride damage is a perlite-related problem and have recommended that you rinse the soil additive in clear water prior to using it in soil mixes. But in light of the available information from testing, you can't blame leaf scorch on perlite, or fluoride, alone.

Stop telling new growers NOT to grow with Miracle grow like it's going to kill the damn plant. Saying it is a "miracle if the plant grows in miracle grow"
It is deff not the best or first choice but is very affordable and can grow any plant just fine.
I am quite sure you can show it will successfully grow fine plants
There is however something you cannot do with MG soil mixes. It will not convince people that they do not need to spend the most amount of money possible to gain a trivial edge. People are driven by desire to say they have the best way to grow or produce the biggest buds. Personally I do not care what they can do.
A 2x2 space is only capable of so much production. Yes you can piss away $100 worth of ferts in a 2x2 space but why do that when $3 worth of miracle grow will work just fine.
There are posts that claim better lighting. There are posts that claim better ferts. There are posts that claim better methods. There are NO cost per pound posts from anyone who claims to be growing bigger or better in a 2x2 space
The one and only thing impressive or of interest to me is what I spend for what I can produce. Nothing else matters
