This isn't just a watering problem... you've got definite signs of nitrogen toxicity so my recommendation is that you flush... Check the PH of your runoff as you do this to make sure you're getting it to end up between 6.0 and 6.5... then, when you feed, cut your nutes in half for the first go-round... if there has been any lockout, the plant will need a gentle reintroduction to the nutes.
btw... you don't tell us what amount of nutes your giving them... if you're still giving them grow nutes, back off on them and stop them next week... they usually contain far too much nitrogen for the flowering stage!
Good luck! Keep us posted!
