You guys have had a bad go with MG, sad to see plants look like that.. I my self use MG organic, But i use a 50/50 MG/perlite. I have yet to have anyproblems with it. The added perlite does wonders for the DRAINAGE problem that normaly comes with MG soil.. Again this is just my own experince, I also used A Scotts mix once that was shitty the ph was way high and it had lots of bark, Very shity...choke with ya'll later
