The first pair of leaf lets with only one set are yellowing from the inside out and the second pair of true leafs are dropping the bright green the plant once had. I'm watering every time its dry. Check it everyday. My lighting is set up to 18:6. Its still a 28 day seedling and is less than a foot tall. Has 5 nodes with two true leafs on each. I peed in a calling of distilled water and am about to start watering it Mondays with it. Any suggestions to why this is happening?
