Help me identify, Tiny white larvae

I have these tiny ass larvae in my coco they are giving my plant signs of deficiency with all nutes and ph dialed in I will post pics the adults I've only seen once and they jumped out of sight like a flea but shaped like a beetle and real small thanks

Bull...mate.......... total Bull! ..bugs don't give a deficiency least not in the way you think,
cut back your nutes until you see some positive action apply
Neem Oil 1 time a day until harvest will see you get a yield
