Best way to add nitrogen during flower

I'm about 2 1/2 weeks into flower and some of the lower leaves are beginning to yellow. What is the best way to give the plants the nitrogen boost they seem to be craving?

I just flushed and am about to start them on a 1/4 strength flower nutes + molasses feeding regimen which I will increase gradually to full strength, but I'd like to take care of the yellowing immediately.

Thanks.

Do you have a healthy diet? Urine is very high in nitrogen. Dilute about 1 cup urine with 1 gallon of water. Apply directly to the soil.

Besides flowering nutes, it's all I use.

Not much nitrogen in worm casts, just give it a little fish emulsion.
With the growth spurt in early flowering all the nitrogen gets used up pretty fast.
It's not a bad idea to continue using veg nutes for the first 3 or 4 weeks of 12/12, otherwise you will lose all your fan leaves too early.

Nitrogenis important for plant fast growing so its necessary to use it properly.

I used this with very good results...it's an 8-0-0 liquid fertilizer...i know, i know it's miracle gro but it's the best i could find on short notice, and i think it worked really well. i was having the same problem as the OP.
