depends on your temps and how quickly they dry out. I usually water every third day. Tap water-175ppm- my nutes are 500-1200ppm depending on the stage theyre in

ok. so use nutrient water every time then?

Just started a grow in coco with 4 clones (75:25 coco : perlite). I've got PBP Grow and Cal/Mag and have been hand watering so far. I've been using RO water with about .5ml/gal of cal/mag and a little superthrive for the first week. How often should I be feeding/watering the plants? I've been watering daily since it's been pretty hot here (I was watering every 3rd day but the clones started to dry), and the plants are doing well. Since it's coco, should I be feeding daily? Nutes in the AM, pH water in the evening? I seem to find a lot of debate about how often to water in coco as well. Everything from twice a day to once every 3rd day seems to work based on your environment. Any help would be appreciated.
EDIT: I decided to drop one of the daily waterings last night. When I woke up this morning, the 2 newest clones were starting to droop, so I watered everything. Since I live in L.A., my air is really dry (about 40% rh in the tent, but I just put a humidifier in there) and it's warm (80-90) in the tent. I'm worried about them drying out because I didn't water them for one day and one of the newish plantings almost died. And you can't overwater coco
