samwell said it best when he called them "shiva rape bait plants".
seriously, clancy, you have $50. you said so. go buy $3 worth of solo cups, $10 worth of good, seed starting soil, transplant what you have, plant some more seeds, and just water with good ol' tap water. maybe even splurge the extra $3 on a few gallons of pure, 0 ppm distilled water.
milk and rice and ashes and halogen and manure are the wrong path to go down. keep it simple.
pro tip: it ain't the lights causing those things to yellow. i have all my veg plants under CFL as well, all green. just take some of the goddamn advice we are giving you because those poor shiva rape bait sprouts are getting more yellow and necrotic by the day.
