i started using superbloom after week 1 1/2 of flowering and its doing a great job, its week 3 or so and my tops are the size of those yellow gluesticks you can buy haha it doesnt hurt to get a bunch of other shit for your plants, but superbloom is pretty efficient, high P, low N and medium K, i put 3 tablespoons per 10L of water every third day and theres a noticeably susbstantial difference
