Easy SM. With what he has,instead of waiting till he can order the correct type of ferts. He could simply increase what he has on the most effected plants. The high K hasn't effected the plants yet because of the low ec. He should be much higher,that's why the P is showing up first,the least available.
Tyga just try it on the worst plants. Bum your ppm up. EC .1 is around 500 ppm depending on the type of ec meter. Way low for the stage your plants are in. Do order or pick up some coco friendly ferts.
The numbers on what you have are no good for coco. P's to low and the K is too high. Gen Hydro, Cana, CN17 and H&G are just a few that are good.
