moisture control soil?

if you MUST get MG go with the Moisture Control, if you can keep getting Fox Farm stick with it. Unless you want to keep a mother I've heard that the time release stuff in MG will keep that slut good-n-healthy.

Moisture Control: nute once your've flushed the soil from what i've been told, or start at 1/4 or even 1/8 strength and slowly up the nutes to see if it can take it.
just my 2 cents

If they're okay now, they should be fine. If they're 12" or more, it's probably time to start some nutes, unless you have a giant sized pot.lol Next time, if you must use MG soil, add a bunch of perlite to it and it'll work even better. I used it for 3-4 grows and it worked great, except for the fungus gnats that came with it. That's the main reason i switched to FF Ocean Forest.
