hi this will be my second time growing. The first time was pretty bad because i didn't get that much bud. I only got like 6 grams if that lol. i am using 2 cfls and floros. I want to know how to grow big bud and the most. I heard something like topping or something but i dont know when you can do that and how to do it. also if you could tell me the ferterlizers i will need in each stage that would be nice.
