Well it's too late for the kick in the but flower cycle nutrient but you should have a good enhancer to provide the proper amount of P & K for this cycle. Awesome Blossoms work well with the GH 3part you are using.

Liquid Karma will help along with the AB but don't forget you will need a flusher for the end. Flora Kleen works well and that is what I recomend to use with AB & GH 3pt nutrients.

There is a chart in the FAQ section you will need to get them through the flower cycle so you know what nutrient mix you need to give them for that weeks cycle of life.

Hope that helps
Zandor Reviewed by Zandor on . Supplements for flowering? I am at day 20 of flowering and was going to pick up a few needed things and was wondering if I should be picking up some extra supplements to increase or make a healthier yield? I currently am only using RO water, GH 3 part, and calmag+. I'm not looking to do anything experimental or difficult. Just wondering if there's any "must have" or "highly recommended" flowering supplements? Rating: 5
