MiracleGro Orchid Food 30-10-10

Hey yo has any one used this stuff on their lovely MJ plants with success??
I found it at KMART for ..$3.99 so its def good for the budget growers.
any feedback on this stuff would be appreciated.. i am a noob and this is my first grow but i have gained alota knowledge from this site and i intend to give it right back... soo i am going to use it and see how my 2 small plants respond and post to let yall know

IVE use miracle grow flower for when my plants are flowering bigger flowers = bigger buds but be CAREFULL YOU MUST FLUSH FOR TWO WEEKS MAYBE MORE DEPENDING ON THE HEIGHT BEFORE YOUR HARVEST SO YOU DON'T END UP SMOKING FERT....GOOD LUCK

ya and when u try to flush mith miracle grow ull kill your plants in a heartbeat unless u flush it slwoly periodically throughout weeks..

my advice DONT USE MIRACLE GROW
