I'm in PA so we have similar climates. Please consider the following:
1. With the level of TDS in your RO, you should flush out your trays regularly. Consider having water that is 100 TDS in the tray. It evaporates leaving the minerals behind. You add the same amount of water with 100 TDS, which absorbs the minerals left behind, so now you have 200 TDS water in the tray. While this is a simplification for illustration purposes, the principle hold. I use 0 TDS ro water but after a month or two when I check the TDS water in the trays, it has increased.
Check your water in the trays! Use a TDS meter. Periodically drain, rinse, wipe dry before reusing. This helps maintain cleanliness as well and slows down pest algae.
2. I agree with the comments above regarding lighting. However I suggest using the light for a longer period of time. I keep my CP's under light for 12-16 hours per day. Moving out of the window could help if sunlight is too hot or bright.
3. I would not let the sundews sit in a tray that does not have any water. Minimum half inch at all times unless there is a specific reason for letting them dry, such as dormancy for some of the species at which point they need a separate tray.
The larger the island of knowledge, the longer the shoreline of wonder.
