Thats all you need for a complete grow. The nitrogen could be brought up to a 8 but many people grow in soil and like the taste of fresh earth worm casting so it is a bit low for veg but works fine. I have a nitrogen boost product if you wish to bring your N up a bit. Nitrogen can be tasted when smoked so even though a plant uses the most N then K then P it is better flavor to keep it a tad lower. I have used most of the organic ferts on the thousands of plants I have grown. The product is designed for maximum yields and as far as I know is the only USDA fert certified 100% organic. I have termendous respect for all the organic companies out there as they have given me many wonderfull memories and numerious headie treats.

One love
