Whatever you do don't use the amounts they call for in their feed charts that have you overfeeding and then flushing every two weeks. Just feed less than they call for from the beginning and skip their stupid flushing the nutrients out of the soil that they told you to feed to begin with. I'll use their soils but you couldn't pay me to use any of their nutrients. I'll grab something off the shelf of Home Depot before I'd use any of their nutrient products and likely end up with a better grow. I have absolutely no use for their cartoon labeled bottles with silly sounding names.
