I first want you to check out any of my signature links as all these plants (minus the miracle grow) were grown with either Jack's Classic bloom booster (10-30-20) or their general nutrients (20-20-20) ($10 for a six month supply for either). Don't buy into the over-priced "weed specific" nutrients.....
Here's a link where you can type in your area code for your closest retailer (mostly nurseries).

Growing with these nutrients is so easy you will feel like your cheating. I feed daily (1/2 tspn per gal) with these nutes and get zero nute burn and zero nute lock-out.
