Having problems with my DWC set up, so I thought it might be beneficial to go to a simpler nutrient schedule. I saw some positive feedback of the Lucas schedule which only uses GH flora micro and blue in a 1:2 ratio.

for seedlings, it recommends half the regular dosage. That works out to 4 ML of micro, and 8 ML of Bloom per gallon. That works out to 5.5 teaspoons of micro and 3.75 tablespoons of bloom for 7 gallons of distilled water.

I added that and mixed it up and ended up at 900ppm on my pen. What am I doing wrong here?
