[FONT='Times New Roman','serif']MANGANESE (Mn)[/FONT][FONT='Times New Roman','serif'] Necrotic and yellow spots form on top leaves. Mn deficiency occurs when large amounts of Mg are present in the soil. Foliar feed with any chemical fertilizer containing Mn.[/FONT]

I doubt it. Manganese is immobile, meaning that only emerging foliage would display the problem. If these symptoms are newly developed, it is probably due to a mobile nutrient deficiency -- probably Magnesium.

I don't have enough hydro experience to comment specifically, but I would drop some Cal-Mag in there and see if that helps. It couldn't hurt.

How much of the cal-mag is sufficient? and also isnt Epson salt an alternative to the Cal-Mag???:confused:
Oh yeah, We are using soil... and we use a pre-soak Resivoir with pump and Air stone.

I would use Cal-Mag as prescribed on the bottle. I have a Botanicare feeding schedule here somewhere, but it's on the bottle. Epsom salt is Magnesium Sulfate, so that will give you magnesium ... I've never used it, so I can't comment on dosage, but if you poke around on here somewhere you can probably find it.
