I cannot seem to grow hydroponic tomatoes, I have tried several varities with different mixtures of general hydroponic nutes. I ALWAYS get tiny pin holes of brown dead plant on the leaves that spread after the plant gets about 4 inches tall, I have no peasts and keep it sterile. ideas?

If it looks like a blight but you know it is not then I wonder if you are using RO or distilled water which lacks Cal and Mag. You need to add calmag to the water if this is the case. Calcium should be maintained at approximately a 1.5 : 1 ratio with phosphorous.
Calcium should be maintained at approximately a 3:1 levels to magnesium.
