Yeah give them a break from the watering and let the coco dry a little bit, don’t want to let it dry completely out but can let it dry til you see some lighter color on top.
Looks like there’s green moss on the perlite. You been overwatering. The first time you flush, lift your pot/cup up and sense how heavy it feels. When those little cups are Dry, they’re light as a feather. Today I lifted my pots and decided to water/flush tomorrow. So tomorrow my super soil Will be Dry, but not my roots/plant. Wait until it’s Almost Dry. Sometimes that means wait another day.
