Flowering plant yellowing

My plant is 6 weeks from the flip currently and it's producing some great looking buds. However the leaves on the plant are yellowing and curling. It seems to only be the lower leaves currently but I don't want it to spread. Is it a nitrogen deficiency and if so should I start giving a nitrogen fertilizer? Does it even matter at this point, the plant should be able to sustain itself till the harvest right?

its a nitrogen issue need help Grow more N30 ,P10 ,K10 very good product you need a good way to harvest. the plant will not sustain itself ,yellowing of leaves will continue to die could affect hole plant.

The plant looks short on Mg. I would tread lightly on feeding additional N, based upon where you are in flower. Good luck.

I gave it three gallons of distilled water mixed with molasses and calmag. Hopefully this clears it up.

My plants do this naturally after week 5-6 everytime. Your feeding it like 0-10-10, or something like that at this stage. Its just pulling the nitrogen from the leaves and maturing. Buds need very little N at this point, so it grabs from the old leaves. Plants have been doing this for 500 million years because they didn't have someone feeding them daily.

This for sure. Why would you boost nitrogen that much in flower? Yikes I’ve had bad experiences with that before. I won’t make that mistake again. I use 2-8-4 or 2-5-3. Keep that N low from here on out.

Sorry for misunderstanding your question Danny, I seen it as six to flip that's why I said it needed N my bad . I agree with both Skewbong & Wattzzup, N must be kept low . Cal/mag good one , deficiency in mag can be seen as a N deficiency that close to harvest .

Which is another great reason not to defoliate during flower. All those leaves are storing the nutrients the plant is going to need to produce big juicy flowers. Yes you can remove some leaves (especially the ones that are very low to improve air flow and access for watering) but most of them should be left on the plant until the plant has sucked everything it needs from them.
