I am looking for a good top soil amendments just for the simplicity and my lack of knowledge. this will be my first grow. I will be using Happy Frog medium. I seen that you were using Earth Dust...but you were seeing some plant deficiencies for w/e reason you said it may have been the auto watering system..I know it's only been a week or so but have you came to a conclusion. I really would like to know your thoughts on Earth Dust or would you recommend something else?
