Swiching soil between veg_ flowering

Is it ok to switch from Miricle grow potting soil in vegative- to Fox Farm in flowering?

is it damaging the plants in a switch?

and if yes then Which fox farm soil is the one I would need most?
thank you

yes you can do it. be careful with the root ball, but try to get as much of the mg out of the root mass as you can. if it's too dense, just transplant it normally. i wouldn't feed it for a couple weeks either. FF soils have about 2 weeks worth of nutrients. either OF or HF are good, but OF has more nutes in it imo. a lot of people throw in some light warrior too. i use happy frog mixed with perlite @ about 3:1.

WHat is OF exactly ? HF also??? Thank you....

what if I continue in the MG? I know your not a fan but what is it that I should do if I continue with MG?

ocean forest, and happy frog. don't really know about the mg....i never got to flower with it. my advice would be to just water it until it starts to yellow, then post pics. i don't know if it'd be deficient, or if the time released ferts would be kicking its ass. that's the prob with mg....it's a crap shoot as to what you are gonna get.

thank you very much brotha IAM
