Nitrogen Diff - Weirdness

Seven weeks into flower, doing 2000 watts with SunShine#4. Have had an nitrogen dificiency for the last thre weeks, fed them the full reccomended dose on the bottle for a week solid, then laid off for a week, the yellowness came right back on about 15% of them, so I gave them half the reccomended dose the last watering they got. Things generally appear nice and green, but some leaves are definitely dieing off and turning yellow. Bud development is real nice, more than I had anticipated. My question is as I am approaching my 7th week of flower this Thursday, I want to deprive the plant of Nitrogen towards the end to enhance flower. It seems I really can't 100% catch up with th elack of nitrogen (tho most look great as I've said) When is the time to stop giving them the N...now? Like I said most look nice and green, but definitely yellow leaves here and there on quite a few of em. Thanks in advance.

Razz...

Generally speakig, in the 7th week many many leaves should not ONLY be yellow.. but they should turn yellow and fall off.... things sound normal..

cheers

Have started to take a bunch off because of exactly what you are saying. I have been told by the person I got the clones from that 9.5 weeks and they should be done. I plan to use MOAB during the last two weeks of flower, so I'm guessing I should now take my regular blooming nutes down by about 25%-50% when doing so? MOAB says should be decreased by as much as 50% at times... I was at 1050 PPM, should I start weening them off now and apply the MOAB in a week or so?

The plant itself focuses solely on creating seeds. The male doesn't do anything to my knowledge but the female drains its energy and puts it into the bud. This is why the leaves and the rest of the plant turn yellow. So don't bother pulling em off because that might cause some stress to the plant.

I have no clue what MOAB is so I can't help you there :).

cheers and goodluck <3

Could cause a tiny it of stress to the plant but if the leat if 70%+ dead its just worth it to take it off. Mold puts its target right on more vulnerable plants, and then speads quick if you aren't on it - just not worth it to me. But has anyone else used MOAB? Do I really need to decrease my PPM of my blooming nutes by as much as 50% like the MOAB says?
