Seems like there are some green thumbs here. I...am not one of them. X) Started some cilantro from seed. All was going dandy. Repotted into a mix of sand, bunny poo, and potting soil for good drainage and some fertilization, in an 8 inch deep pot. It is sitting under a t5 bulb. Did great for a week, shot up, leaves got their toothy edges. Overnight, they flopped over, and are just getting wiltier. Soil is moist, but not soaking. Any tips?
