I think you mean K, K is for potassium, P is for phosphorous, but yes it should not deteriorate anymore if it is potassium deficiency and you dose potassium. Old leaves will not repair the holes.It's most likely the P, like Zapins said. The damage doesn't look great enough to make it irreversible, your crypt will come back like a bad ass once you get those ferts in there! You'll be amazed![]()
Hard to tell what species it is, but I'd guess the upper left plant is riccia which is usually a light green color. Bottom left dark green plant looks like moss. Also, in general there can be only one deficiency at a time. Only one!P.s., the plant(moss?) in the uypper left of your photo also looks a little 'yellow', probably low on nitrogen. Could be your camera though lol....
