Beginner-i too use the biobizz line and don't forget to keep adding your grow to your nutrient feed during bloom. also, you can use the alg-a-mic through week 6 of flowering. its great for your soil or medium. i only used the bloom the 1st time. i finally came across their feeding schedule and made the proper corrections. the improvements are significant. i also use budswell-a liquid mix of worm castings,seabird guano, and bat guano. you mix w/ water and apply everytime you water. its a great way to cheat and get a quick easy way to feed your plants an organic tea inbetween feedings. its great stuff to use after the 3rd week of flowering. good luck!!!!
