Ceg4048, thanks for the reply. Obviously I dont misstrust Barr and his ways since Im a lifetime member. However, Ive used EI before with BBA up to my ears. Ive had good CO2, high nutrient levels etc. (No livestock, so I could push CO2). It didnt work for me. With smaller nutrient levels ive managed to keep it AWAY.
Obviously im going to UP the ferts untill the problem is resolved. But If i could keep them down and only UP, lets say K, then i would be happy.
Im only looking at my waterreport to tell me my Ca and Mg ratio. And to tell me if I really need a GH boost.
