I run by PPM instead of EC, so I'm not 100% certain of how strong your nutrient solution should be.
I'm finding out that my not even 2.5 week old plants can handle 1100ppm(95% of "full strength"), but I'm in much smaller pots for the time being.
James06 - Use 100-120ppm of CalMag until you get to the final 2 weeks
on a .5 conversion scale my ppms would be 700 first watering, 750 second watering, and 800 third watering.
