STarting from seed, my zinnias sprout quickly and reach about 2 inches. They have their first two leaves, but never show their "true leaves" since the two leaves always start to turn brown and then die. I bought good mix (or so I thought . . . miracle grow potting mix)) what is the problem? Might it be the temperature of the cell packs, cuz they arent very warm)

Zinnias are occasionally subject to damping off and other fungal problems, so to minimize that you would want to use a relatively sterile soilless mix, ensure good air circulation, avoid overwatering or wetting the foliage, and also provide very bright light such as that from a fluorescent shop fixture with a "warm" color bulb and a "cool" color bulb with the bulbs kept just an inch or so above the leaves. Growing on temperatures should be about 65 degrees, lower temperatures will cause slower growth. I hope this helps you trouble shoot.
