tips are getting yellow

[yama102106]

ok so its been about 2 weeks now and everything has been good. but now just the tips of the first 2 leafs that have come out are starting to turn a little bit yellow. along with that the leafs look like they are losing a little bit of green color. any help would be much appreciated.
