I am a new medical marijuana user. I have never grown anything in my life. I have just built a 4'x 5' grow room with all your help. State law allows up to 6 plants. I have just inherited 5 ten week old plants that are just starting the budding stage.Im using a 400w switchable ballast system with the hps bulb for budding.The guy who had these was using miracle grow tomato food mixed in a spray bottle and pretty dilutedas well. What to do next guys? Should I change the food? He was using a 70w hps so this is a good jump for them. My room is well vented. It is staying at 79F, and 58% humidity. The plants are about two & half feet tall and seem in good health. Any help is appreciated!
