I think underwatering combined with the light being close has caused my issue. However older leaves have also dried up and died (but staying green).
The way the leaf looks with yellowing though, and because a couple of leaf stems are turning reddish, maybe it's K deficiency?

To me it looks like a calcium deficiency or a cal n mag deficiency. The yellowing of the leaves outside to in and the brown/ burnt looking tips and splotches are all its trademark signs! I'd say give her a decent size feed of cal mag supplement and u should be able to mend her health and prevent the deficiency from spreading and worsening! Happy growing and stay lit fam

I think it’s a to short of magnesium or calcium. Add some Calmag supplements to your water and they will be better soon.
Good luck

* Spots (pic 4), on only 3 leaves of the plant at the top.
Last week, before lights out, I misted. By lights-on time, some parts of the plant were still wet. Is this some water burn?
Tap water is PHd and ~215 ppm (plenty ca/mg)
* Any insight on those yellow tips is welcome! :)Week 6

Please take a look at the last photo of week 10, the close up of a cola. Does this appear to be the start of a K deficiency? There is tip burn on some of the plant as well. Refer to my notes with watering issues for past 2 weeks. All nutes listed ph ppm are correct. Thanks!!Week 10

Upper growth leaves and buds on one plant are burnt. I attributed this to light damage and raised them up a few inches. If anyone has any alternative thoughts or suggestions about how to minimize existing damage that would be great. Other bud sites look fine.Week 7
