Success nutrients has changed our entire business from struggling and barely getting by to a thriving business with amazing products. The entire line should be used. Without the entire product line you may have some success but will only achieve the best results when using the entire line. As all grows may differ you will need to adjust this nutrient line to certain strains. It will take at least one to two cycles before some strains are completely adjusted to this nutrient line but when they adjust you will not recognize them. The flower will be bigger with more frost than usual and the terpenes will be exploding in your rooms. For more visual proof check us out on Instagram @ evgrowers. Thank you Success Nutrients and three a light.
