What are the signs of needing nutrients

[Smokenpassout]

I have been growing in FFOF. I keep hearing at week four or so its time to slowly add nutrients. I also hear to watch your plant for the signs of needing nutes. What are those signs? So far my plants is green and lush. But I did notice some slight brown specs on a few leaves about freckle size here and there.

Begin feeding with 1/4 strength nutrients. No more than 1/4 strength. Feed, water, water. Do not overwater - the #1 cause of unintended plant death. The nutrients can enhance plant growth and not just medicate it.
