Rule #1 Never use full dosage on the bottle.
When u do veg and bloom build it up.
Week #1 - 1/4 strength
Week #2 - 1/2 strength
Week #3 - 3/4 strength
I never go above 3/4 strength on Advanced Nutrients. Oh and compare dif brands too. yes, AN has some good stuff, but other makers have the same product for less than 1/2 the price.
Compare like AN Rhino Skin to Botanicare Silica Blast. Same product for like 1/3 the price.
Do research and compare product ingredients and amounts they ask yois isu to use.
Yes, you may come across a product that might be 1/2 the price of another brand, so it sounds like a good deal, but when you read how much they ask you to use it could be 4x the amount you need compared to the other brand that may be a lil' more expensive.
So the cheaper brand may be worse because you'll need 2 bottles of the cheaper stuff compares to 1 bottle of another brand.
So really pay attention to the labels.
I believe Advanced Nutrients caters to different types of strains I know they have the Kushie Kush Nute which has worked very very well from what I have seen
