What soil are you using? How many feedings? What all are you feeding? Show pics of the plant and it might be more clear. I feed a N boost a week after 12/12 to help w/ the stretching and fast paced growth they do to make room for nugs. If your strain is a fast feeder and you vegged long then you probably have a deficiency. Check out a deficiency chart to help diagnose.

Yeah I switched to ginormous by Humboldt, honey es by Humboldt, calimagic, and earth juice micro nutrient. I water them once every 7 days or so in 5 gallon pots. I do feed, feed, water. PPMS of feed come to about 1000ppms with everything listed above in it Here is a pic of the whole plant. There were those two leaves on the top part near the cola and there is one left near the middle.

It's normal if you quit providing nitrogen as the buds are rapidly growing. That does not mean it's to your advantage, just to be expected as you watch the plant starve.

Personally I see a magnesium deficiency, brown crispy leaf tips pointing upwards. Probably caused by over use of P and K without elevating the levels of Ca and Mg to help compensate.
Crispy brown leaf tips that curl upwards will be followed by rust or pale coloured blotches on the leaves, followed by white necrotic spots then followed by yellow dying and falling leaves.

Switched nute? Do you ririse with 1/4 strengh first? Remember if you are over feeding them, and even if the pH has banged around, remains out of range, etc, you get lockout.
And that means you are not feeding at all. And you will begin to present all the problems. You can't chase it.
And that has always been a question for me in all these soils. It is why I use coco coir. What do I do in these supposed wonderful mix concoction, if I do see a problem.
1000 ppm ??? Are they nearly big enough for that? Over feeding?

Oh, well. 6 ft qualifies.
Almost there. Soon you will be backing down feed.

N is a mobile element. late in flower its normal to see it being taken from the bottom and moved to the top. you're 6 wks into an 8 wk run. don't get too hung up on a few yellow leaves.

You have a little tip burn. You should feed, water, water. Make sure to get a little runoff the first water after feed. This helps flush whatever the plant didn't use and keep from salts building up. If you feed after a feed in soil it most likely will almost double your ppms. This can be toxic for the root zone and give you too much of one nutrient to where the plant locks out another. Example: Too much P can lock out Fe.
