All of my cannabis plants have the same soil mix, and have been watered about the same time once every few days. Except my 2 bigger plants, these plants you can tell the most of the issue. It was huge and I tried filling up the net then all the leaves started turning yellow and dying off. I noticed I have spider mites, and have been trying to take care of them also. However the yellowing of the leaves is taking out the plant faster then the mites. The trichomes on the buds seem to be all cloudy and the other plant has like 10% amber. If it comes down to it I'll just cut them. I'd really like to solve the issue before it affects my other plants though. Sucks it's taking out the older ones pretty bad.

Your using a soil less mix that has no nutrients. Lack of nutrients is the cause of your issues. All you need to do is buy cannabis fertilizers and follow the instructions. You will end up with much much larger plants and the lower leafs won't turn yellow and fall off
