Nitrogen deficiency in late flower

[kudzu]

can i give nitrogen in late flower, when plant showing deficiency? will that hurt flavor or aroma of final product? harvest around 7-10 days from now.

Best to post pics anytime you have a question about plant health. Not much nitrogen is needed in late flower.

i read earlier today here somewhere that too much N in flower slows the ripening

passing it on

If you are a week out from harvest it’s not nitrogen problem, the plants are just finishing up.

Yes you can. The plant still need nitrogen, all the way up to harvest, but as @Pantagruel mentions, not much is really needed. Just enough to maintain any new green growth of which there is very little, just a few sugar leaves and maybe a calyx or two forming. The plants use the nitrogen for photosynthesis so again, not much needed.

If you are seeing some pale yellow leaves showing up it is another story. The nitrogen that was stored in those leaves for photosynthesis has been used by the plant the minimal new green growth and any photosynthesis in the upper part of the plant.

Since the harvest is in 7-10 days there really is no point in worrying about this anymore. Any small amounts of nitrogen given to the plant will not have enough time to have any effect. Many growers report that changes from adding most nutrients will take 2 weeks, give or take, to show up.

At this point don't worry about it, relax, sit back and prepare for the harvest.

Yes, one photo showing pretty much the whole plant will help make sure we are all talking about the same thing. Just take the photo without any purple, yellow, or red grow lights turned off. Use regular room light and put the camera on auto flash. This will give a photo with natural colors.

I don't think you have an N deficiency, that's just normal for late flower.

Yes, pretty much a late flower condition. Not exactly a deficiency but the leaves have turned yellow because the plant has been sucking the nitrogen and some other nutrients from those older leaves to promote healthy growth in the flowering. Not much that can be done about it since harvest is now a week away.

Some growers will go out of their way to keep the whole plant green right up to the last day and some growers just accept what happens as long as it is very near the end.

IF anything is going south its from TOO MUCH nitrogen. Just water down the stretch and watch for the pretty fall colors.

It's called senescence. Too much N and your weed will be very harsh tasting for several weeks after harvest.

Cannabis stores N in fan leaves and translocates it to the flowers not from the roots. Its just how plants grow.
