Too much nitrogen and my plant has gone dark green...

This is my first outdoor grow and my best plant got over fertilized. Slight nutrient burn on tips and edges. (not very bad)
But it has gone a dark shade of green when it was a lighter green less than a week ago a few days after i put on the fertilizer.
I heard too much nitrogen can cause this..
Anyway will it recover?? Because it the middle of summer and not far off flowering stage.
WILL THE DARKER LEAVES WORK AS EFFECTIVELY IF THEY STAY DARK GREEN??? OR PRODUCE LESS BUD?
\they are in the ground btw and i have been flushing soil...
burn isnt getting worse. growth may be slowed not really sure..
HOW much will this effect yeild..

If she is flowering then yield will decrease. If she vegges a while longer then most of the N will be used. Just use plain water for a while.

It should be vegging for a little while still. BUT if it uses up the nitrogen and the new growth is a proper shade of green, what hapeens to the old growth?
Will it still function as well????

any pictures? I think you'll be OK since outside is much more forgiving. How often do you water?
