To my knowledge (limited tho it is) it's sometimes normal for t's to go off food a bit before a molt, and considering the size it would be too far of a guess. Also it's somewhat normal for the grammostola family to be picky eaters G. Rosea perfect example. I swould only really get worried if the activity level begins to decline, or you notice odd behaviours.
One weeks fine, tarantula's can go a lot longer than that without eating, so don't worry. In fact, most people usually only feed their T's around once a week, the less you feed them, the slower they grow, the longer they live. If they're hungry, they'll eat, just make sure you either mist a little bit, or give them a small cap of water, depending on how big they are. As long as they have water, they're set. My Poecilotheria Ornata doesn't eat a whole lot either, i used to give him 2-3 crickets a week, however he would only eat like one, and i'd just have to take the crickets out after them being in there for around 24 hours, in other words, i'll give him a cricket, and if he doesn't eat it by the next day, i'll just take it out to avoid mites or other nasty little bugs. So don't worry, your T may be going into premolt, where it'll darken up, move less, and hardly eat, or it could just not be hungry, simple as that
could also be because of new surroundings. did you rehouse them?
if their bums look ok, i wouldn't worry.
you could also try smaller prey items? seems likely because it's #2, the smaller one that's not eating. something just under 1/2 their leg span should be ok - cut up mealworms, cricket drumsticks and my favorite - pinheads/ baby crix.
what do you feed them?
and since no one's asked, how's #3 doing?
