my girls had mg difenicy and I cured them. It is 3weeks later and it looks like its back with copper, p, and k difenicy. the fan leaves will not open, they have no smell, they are not growing, but the bubba kush looks like it sill growing tall, the rest of them are not growing at all they have brown spots on the leaves and they are turning yellow. they also curling under and getting brown at the tips. I need cheap ways to come up with a solution. by the way I may have giving them to much epsom salt this time around for the mg dif.
