Day 29: Solicited some opinions about what was going wrong with the plant and got some more opinions. Learned I should be watering more, enough so that some substantial run off occurs. So poured about two gallons into the pot, supplemented with CalMag. (also put another 1/4 cup of Coast of Maine Plant food in the soil.
Runoff PH was 6.5, so that did not indicate a problem. Hopefully the flush will turn it around!
Also downloaded the Photone app to try to dial in the lights about. Lowered the light height in order to get the numbers more in line.
