It seems my problem may be the exact opposite of mosts. Because of all the book reading, post reading and online faqs, the idea of overwatering or overfeeding became my biggest concern. As a result, I've been starving them. If they did get any nutes, it was barely anything but tutorials for soil don't work for coco. The medium has no nutes so seedlings probably need a little help earlier than in coco than soil.
At any rate, I just gave my plants a nice healthy dosage of nutes around 3 hours ago and I can already see the edges of the leaves getting darker....so we will see how it goes.
