Hello, can someone please help me identify which nutrient deficiency I have in my hydroponic system? My leaves are turning yellow. I think it might be iron or nitrogen, but I am not sure.

If you are using stripped/filtered soft, low to no EC water, then you should add a half dose of Cali Magic to your garden every time you top off. Questions? Comments?

Anyone adding compost tea or microbial inoculants to their systems? I currently add EM-1 to my towers every week when I top off. I'm planning to experiment with compost tea in the future. I compost for my potted garden and there is always enough to go around. Wondering if anyone else is doing this and what results you're seeing.

Anyone using copper algaecide or some kind of ionizing copper for algae? Thoughts? Opinions?
