First time coco grower

Hi bud, as I understand it you need a good wet/dry cycle... Think of it this way, if someone held a damp cloth over your face could you breath? Them roots need oxygen too, although at night they take in co2 but that's a different ball game!! Try letting them dry out a bit, not Sahara desert, but you know dryish, if the leafs start to "perk up / pray to the light" your onto a winner, always best starting at the basics, get them nailed, and GROW from there, all the best, happy growing 👍
