Nitrogen toxicity

Time to flush. No way to really get rid of it quickly other than that. Adding sawdust or cheap dyed mulch to the top of your soil will draw it out but much slower than flushing.
 
Proper Nutrient Management!!!
1) MANAGE your grow and do not apply excess nutrients in the first place.
2) flush with plain water (regular tap water may be the best option in this case) but please, collect your runoff and go water it on something else.
3) if it's frozen outside and you have no house plants, well you are stuck with the responsibility of that rinsate. Bring it with your used motor oil, old batteries, and computer monitors to a recycling facility.
 
First of all, welcome to GWE.
There is a host of information on the mainpage about yellow leaves.
Yellow leaves turning brown is not a sign of nitrogen toxicity.

To directly answer your question: No, don't just flush when your leaves are yellow and turning brown.
 
One of the most common symptoms for Nitrogen toxicity is when the leaves turn to a darker green, and the tips curl downward.

I had to face that in my previous grow, flushing with pure distilled water (PH 6.8-7.0) worked perfectly for me.

Mentioning, for the next 2 days after the flush, i just got the lights abit faraway to prevent stressing the plant in that poor condition, then got them back to their sweet spot again.
