I just recently purchased some fox farm nutes online. I got Grow Big, Big Bloom, and Tiger bloom. this is my third indoor grow. the first was just any good cheap nutes i could get at walmart and the second grow was all organic tea mix. this time i wanted to try fox farms to see if the hype is all that is says to be. my plants are 8 days old from seed. i have 7 in a 3x3 grow tent with 400 watt mh in a homemade cool tube. the temperature usually stays between 78-84*. I am using organic soil and it ph's at 5.9-6.4. is it still too early to start fertilizing with this stuff or can i dilute the amount. most of the plants are around 3' tall.
