5 weeks into flowering. nitrogen def ?? help

Alright so I am 5 weeks into flowering and two of my girls are really starting to show a major nitrogen defficiency. By major i mean all the fan leaves are yellowish green. Mostly yellow. Some of the other plants are starting to yellow also. I know that this late into flowering have a N defficiency and yellowing leaves is pretty common , but the whole plant ? All new growth and bud sites are still green however. I could post some pictures but I described just what you would see.

-Strand it dumpster from clones
-Growing in 5 gallon buckets
-1000 hps light
-temperatures range from 69-85
-nutes using are foxfarm big bloom and tiger bloom
-also adding mollasses to about every watering

I'm 4 weeks away from harvest should i just ride it out for two more then flush? Or should i add a fert high in nitrogen ?

this is normal, all your fan leaves will eventually brown and fall off, just dont pull em off, or add more nutes. If its an indica strain, flush from the 6th week on, but dont worry fan leaves fall off.

I should continue using the big bloom and the tiger bloom shouldn't I ? I was going to continue using water and mollasses- nutes and mollasses - water ..... for about another 2 weeks. then only feed with water and mollasses. does this sound correct ?

don't worry about it...

I'm also in week 5 flowering and have some major yellowing. Some plants more than others. But I also noticed that the ones with more yellowing are more developed.

This is one of my yellowing NLX':

checkout a similar thread I started a few days ago. some good advice there https://www.rollitup.org/marijuana-plant-problems/159976-deficiency-nute-burn-salt-buildup.html

Plants will yellow when they get close to being ready to harvest, like what, canola and other crops. Sounds like you are on the right patch at your stage do not add nitrogen it will only cause the buds to streach and become fluffy.
