jeeeez! that's almost freezing, i'd definately get a heat pad for em or a mini radiator... or bring them inside at night, they shouldn't be getting that cold though

p.s when watering, i always water the entire soil area to encourage the root growth.. if you only water the area directly around the plant...it'll start to suffer
