    I have a situation I canonly describe as rust forming on my leaves. They are about 30 days old,are clones in soil(pro-mix) under 400w hps. They seem to be stunted after a great start. I am using foxfarm grow every other watering.It seems like a mineral deficiency as I can not find any pests. Could this possibly be a magnesium deficiency?
