Six molts in one week!

So it appears my little collection of itsy bitsy spiders has decided to have a molting party. Six molts in the space of one week three in one day! Unfortunately my Aphonopelma sp. (paysoni) did not join in on the party. I've been waiting for that little one to molt for over a year and a half now. Its the only one who has never molted for me and it's getting quite rotund and could use a good growth spurt.
