Should I continue to feed/water cycle or do another feed due to the light color of leaves?

Hey man imo it might be a PH imbalance issue from your last feed. It's hard that she is deficient from any nutrients if you are feeding regularly and you didn't overdo it because leaf don't show off any signs yet. Nevertheless i have had few strains that changed to a lighter green once they hit the flowering stretching phase so it might just be that.

That one plant needs more feeding than the others.......all plants need their own schedule of fertilizers. Just giving them all one generic formula can lead to exactly this outcome. Remember though....what is showing now in the leaves, is a direct reflection of what was occurring in the root zone 2 -3 weeks ago, so this problem is already quite advanced and one extra feed is not going to "fix" this. It will take a few feeds over the next 2 weeks or more to show total recovery. Feed as normally, as in time intervals, but increase the strength slightly for just this one plant, the others look fine and obviously don't need as much food as the pale hungrier plant.
