I'm a new grower and will be growing two auto amphetamine plants in 5 gallon drip ring systems. I have a question about which nutrients to use. Right now I have bottles of AN grow, bloom and micro. I also just received for free a bottle of AN sensi grow A and grow B. Which is easier for a new comer to use? Should I go with the g/b/m or should I use the sensi a/b grow and buy the sensi a/b bloom? I really don't want to spend more money on nutrients, but if it's really worth it, then maybe….. Thanks!
