No one know anything come on ???????

thats the start of whats called "interveinal chlorosis" chlorosis is when the plant turns yellow, if the leaf turn straight yellow/pale thats Nitrogen, but when it starts between the veins it could be from 5 different conditions...make sure your PH is proper and you have well balanced nute solution with all the major and minor nutrients
