This is just from my experience and I think a lot of growers would agree and that the plant will let you know. As in the leaves will begin to turn a light green. This is the point where you want to add a weak amount of nutesw 1/8 per gallon is a good start. After you add the nutes watch the plant over the next couple of days and you should see a turnaround in color from light to dark green after a day or two. After that just incrementally increase the amount of nutes per gallon. Hope this does it for you. let me know how it goes.
