The baby seedlings started to yellow then the spear leaves started pointing upwards, now the spear leaves are wilting. What's going on?! Nutrient, lighting, air?
What type of soil? Seedlings are very sensitive to fert/nutes, the less the better. If your soil has a lot of nutrients in it (most MiracleGro and the like do), then that could be burning your young plants. Also, marijuana does not like overly acidic or alkaline soil, you want a pH of or around 7.0 (I try to keep mine at 6.3 actually). If your soil is too acidic or alkaline then you start to lock out the plants ability to take in certain nurtrients. It also causes the plant to grow deformed. As everyone else has said, with no pictures, it's kind of hard to diagnosis your problem for certain.
