so I had this holy vrap moment when I had to understand coco. Like ok so too much water overwaters, then how to I water everyday ? So the cool thing about coco, is it is a hydro medium but without the buckets and reservoir. There is no chance you will overwater in coco perlite, absolutely none. if you water daily, the medium will be saturated enough that the exchange rate will be so that you would not need large quantities of water. But when you let the coco dry out, all the nutrients buildup and dry out with the coco making it harsh, so you get a droopy plant that looks like it's been overwatered. PH will be really off when it's left to dry out.
What you want to do, since you are letting your medium dry out, there will be residual nutrient build up, take the ladies and do a mini flush with them and make sure the water is ph'd. Ph water at 5.7 ish because your ph in the medium will be high. keep flushing till the water running off is not murky anymore, if you have a ppm pen, you make sure that the water running in is the same, or a tiny bit higher when it comes down from the pot, once the ph range is where it should be you add your nutrients, because that little flush just washed most of the residue away, so you want to maintain a nutrient balance so once you're done with the flush you feed your plants with your regular
