Backyard Aquaponics
A place to discuss aquaponics

I have some black spots appearing on a few of my tomato leaves, not all of them. One 'organic' gardening site I found recommended a Copper Oxychloride spray but a quick look at the MSDS has me running far far away. The minister for war and finance has found a few dozen home made recipes but I figured this forum of aquaponics geniuses would already know the best cure.

Any help please?

It depends on whether the black spots are caused by deficiency or disease.

Some good clear pics would help. Some close ups of the black spots and some of the entire plant.
