Is it too soon for my leafs to turn yellow?

I am aware that my big fans leafs will start to turn yellow as the flowering stage gets closer to harvest. I have 4 super skunk plants growing very well and are 2 weeks into flowering. At least one leaf on each plant is starting to turn yellow.
Is this too soon to be happening. Could it be something else? I noticed it last week and the 2 watering after I didn’t put any nutrients in thinking maybe I was giving to much. Any suggestions would be appreciated thank you.

It is normal for bottom leaves to turn yellow as the plant matures. If it start creeping up the plant come back and ask.


Not sure your inside mine are out same strain. I feed every 4 days or so they get very hungry at this age.
