The LaMotte Nitrate/Phosphate test kit I am using only reads levels to 1.0ppm Nitrites or 4.4ppm Nitrates.
Last week I brought the Nitrate level up to the 4.4ppm level without realizing that I had maxed out the level the test kit could read.
So yesterday, after realizing what had happened, I decided to keep the level at 4.4ppm Nitrate. I have been testing the solution before I added any more (for transpiration/evaporation loss) just to satisfy my own curiosity.
The new plan: Monitoring weekly:
I will continue to keep the Nitrate level at 4.4ppm to see if it affects the duckweed while monitoring the level of Nitrate it uptakes. The evaporation/transpiration loss has been consistent at 70ml for the control and 80ml for the plant dishes.
BIG Thanks to Dr. Woodall for the title of this post :-)

You're so funny! Since we're running short on time..why don't you shock them with stuff and I'll bring down the Hach Coloromiter so we can measure what killed them. That would be fun to finally say...I GIVE UP...I'M DEAD NOW!! :-)
