Yesturday I went out, and I came home to see a yellow urate in my plateds enclosure. Today I found out for sure it was from my female plated as she did another one. I know this can happen when they are on a poor diet or if they are dehydrated. I don't think it could be down to any of these as

1) They have a good diet of fresh food and live insects.
2) she is forever going into the water and drinking it.

Does anyone have any pointers as to what to look at next?
