i found this in my garage can i use this for food and if not any suggestions of what to get and if its avaible at a local home depot Osmocote flower food http://www.amatteroffax.com/itempag...s-company-osmocote-flower-veg-plant-food.html
You CAN use that, but it will suck. Look for epsoma brand if you want something like that but better. Or google grow stores in your area and get some proper nutes. Kelp and alfalfa are cheap and easy super foods for MJ. Kelp, alfalfa and molasses are enough to get you through the entire grow. Add some worm castings, compost, and guano and you will be doing great. If you are interested I can give you more info on how to use these things. The first step is buying them.
