What size pots are the plants in, what’s your medium, and also what is the thought process behind changing the lighting schedule?
With regard to water, an extra hour of darkness isn’t going to make a difference.
Water in the tray isn’t a good idea either, as you’re likely to massively over water and drown them.
I’ve left fully watered plants, in flower, for 5 days (5 gallon pots), but they were in bad shape when I got home
Best possible option IMO: Get someone to plant sit
