The person you talked to at AN probably never grew a daisy, let a alone weed. They just regurgitate whatever the higher ups tell them. I wish they would test their products under LED and then see what they have to say. They use to sell calmag supplements, I was on their website the other day. It's no where to be found. Not smart on their part, but I'd rather use botanicare brand anyway. Don't get me wrong, I love their pH Perfect line base nutes.
