Your girls look good. Looks like the big one is going to need another transplant soon, and the other 2 aren't far behind. But I'd worry about the drooping leaves. It could be over or under watering, but it could also come from the roots being eaten.
I've never seen a worm like that, but I'm no expert. If you can't find any info on it, I'd buy some nematodes if I were to & get rid of whatever that is.
Don't know what a wood louse is, but it doesn't sound good. This is why I was saying to set up a regiment of treating for bugs every 3 days or so, growing in the attic is going to leave them open for infestations. Be glad you don't have mites. Again, lady bugs wouldn't be a bad idea either, or cleaning out a closet & bringing them inside. But if you have to leave them there, I'd get some lady bugs & spray them every 3 days with different oils (Mite X, All Season, etc....) Bonide has a few good ones
www.bonide.com You should keep changing the oils every spraying so the leaves don't get dried out. And always let them dry thoroughly before putting them back under lights.
Adding UV light may help also, many bugs don't like it. You can get a 10.0 UVB Reptile Bulb from a pet store and a cheap fixture for it at Wal-Mart. Just don't put the UV light too close right away. Start it at about 3' from the plant and move it closer slowly as the plants build up their "base tan". And always wear sunglasses with UV protection when working around them.
Of course moving them inside is a much better idea, but if you have to leave them there, then these are a few ideas.
You should make getting rid of those worms priority one if you don't know what they are, and whatever soil you used, don't use it again. The worms probably came in with the soil unless it's a larvae of something else.
Good luck with those critters. Peace
P.S. You should start thinking of adding grow lights soon. If they haven't done it already, they'll start to slow their growth pretty soon if you don't give them bigger pots & more light.
