when growing in coco you do not want the medium to dry out. You can treat coco like soil, but why. Once your roots get established you want to feed multiple times a day. Every time you water the coco you are giving the plants fresh oxygen. I'm still new to growing ,but I try to get the most out of my plants, in the short time that they grow. Once the roots get established you seriously cannot over water in coco.
Everyone has there own way of growing, especially in coco. My 2 liter containers are being fed at least 3 times a day. With multiple feedings you can use lower ppm in your feed if you notice burning.
Sorry for the rant lol.
You can overwater any medium really, overwatering is the [HASHTAG]#1[/HASHTAG] issue in all new gardens, when you first transplant, give the pot a shake to see how heavy it is, every time it feels light, it's time to water. Once you have the overall water consumption of a given strain down then you can automate super easy. Coco can also go dry for the most part as it's hydrophyllic aka loves water, peat on the other hand is hydrophobic that's why you see wetting agents in peat based mediums, I use poly film on top of my pots so the medium never goes dry, and the white poly diffuses light. It's amazing how much light is lost to the dark pots, soil, flood tables.
