Since everyone else seems to be posing on the lighting issue ill get to the food and
bath issue.
Salad.. since she is a adult best for her is mustard,colard, turnip, endive, dandilion, escrole any one of those will do. She sould have a fresh salad everyday best to add cold water to it to keep it fresh longer(and when they eat it they get the extra water). You can add other stuff ontop. I think the bugs you are feeding is enough for a adult beardie. Carrots arent really good for beardies as a meal maybe a few here and there sprinkled on the salad.
As for baths they need more than once a week. Might be why so long inbetween poops or she isnt eating enough veggies. I would try and
bathe her every other day 20 full mins. to every three days max just to keep her well
hydrated. And most likley why she pooped so much in 1 day is the carrotts didnt sit well. Since that sounds like the only thing she ate veggie wize. That isnt uncommin. If i feed one of mine something they dont normaly have that happens to me too and i take very good care of my beardies. Its nothing to worry about it will pass.
I wouldnt leave the crickets in her viv only reason why is that they will bite your beardie. The bites can get infected and cause health problems. And it hurts them to be bitten.
I hope your beardie gets to feeling better soon.
