nice work man! how often do you water? you may not have an issue, but i believe i had one early on.
it's tricky because you gotta try and keep the seedling roots moist constantly, then slowly spread out the waterings and increase watering amounts. Remember! Look at the size of your plant, and ask yourself how much water it needs! Small plants do not need THAT much water. hope that helps =p
good sir! yes i do like that top-down pic of that clone.

mmmmmmmm. so pretty!
