i use MG 3 month realease mixed with Hyponex soil (its made by the same company that owns MG) and i mix them with a tropic soil mix... i use Hyponex because its 2 dollars and it doesn't have NPK, which helps bring down the NPK in the 3 month release that can hurt seedlings at times...and i like the tropic mix, just because, don't have a real reason, i just think it helps (maybe its all in my head).... but i also sometimes just mix the 3 month with the Hyponex... but when its time for the first transplant, i'll add MG perlite...it works for me.... but basically, what i'm saying is... you can mess with MG and make it work, just gotta know what to do with it and how to handle it.... many people will try to detour you from it.. but thats there opinions... and there are different methods to watering... some pour water into their containers, i personally like to use a spray bottle and mist the soil twice a day... don't have overwatering issues....but good luck and don't worry... just show patience and things will work out
