ok so im on day 20 of veg.. no signs of any defficiencies so far! had nitrogen defficiency on my last(first) grow on all of my little girls! this time i am using a soil that has barely any nutes in it at all so im finally looking good. the question i want to ask is.. when should i start putting Blood Meal into my plants soil? at 30 days you think? i am already aware of only dosing my girls with a 1/4 amount of what is instructed on the contents package. learned that the hard way from over-fertilizing with my last grow!! tell me what you guy/gals think about feeding my girls nitrogen at day 30... thanks its appreciated!
