she liked the added N and iron. Some strains do not tolerate the added N if you need to use a bunch of calmag for RO water and coco coir medium, like i did. She tolerated it greatly.
Ive used FF on a few grows. Overall, i think its a great beginner nute company. Using these with RO water was not ideal. PPMs were hardly ever above 1000, with giving more than the recommended amount.
