justmmjanswered grow question 4 years ago depends on what your want if you want to go the synthetic route I would get a dry fertilizer so you don't worry about the exp date. All you need is the base nutes and feed what the box or bag tells you at quarter strength and increase to full strength over time. Then I would get pressed kelp and ful power and foliar feed with that 2 twice a week and your plants will explode. Make sure to also water with the Fulvic acid
