Michkaanswered grow question 6 years ago Hi there ! Some nutrients are really complete, so you don't have anything more to give, some others need extra boost... My opinion like Athos said, a good nutrient basis avoid to add other stuff, specially when you're a beginner.. Then, when you know your strains, you can guess what she need just looking at her, and give some more micronutrients to help increase your yeld, but it's expensive for the result.. Just havea good PK for the flowering explosion (week5/6) should be enough !
