The really purple stems is not really a good sign. Healthier Plant = Healthier clones.. but if I was to gander why one would be drooping.. Is that it's not rooting and is not a viable clone.. You can try very very gently tugging on the stem. If she is rooting you will feel resistance.. If she has not rooted then she will come right out.. Not the best choice really but I'm guessing you clipped and went to soil.. If you made sure they rooted before you transplanted then it can be a lack of aeration or under water situation.. They don't look dry.. I don't like clones too much because of all the "fucking" around so maybe someone else will have a better opinion/idea.
