Leaves on flowering plant getting dry and crunchy

[Imaginereality]

Hello. I am looking for a little bit of advice here. This is the first grow i have ever attempted so yeah. You know haha.

- Currently 46 days into flowering
- fox farms happy frog soul
- 2500P LED light
-HyrdoFlora 3 for nuts (plus calmag)
-5 Gal fabric potters
- 1 cheesy berry, 1 GDP
- Temp consistently 72-77
- humidity 40-50 (sometimes gets to 37 but it’s fairly rare)

Previously all seemed to be going fine , but as of maybe 5 days ago i started getting these crunchy and dying leaves.

I can’t imagine it is time to harvest yet so i was stumped on what it could be.
My best guess was maybe too much nutrients or something of that sort.
I have been feeding only filtered water since this issue occurred to potentially “flush” them in a sense if that is the issue. But i really have no idea.

Would also love some input on how much longer these should go? My best guess was around beginning of December, maybe January?

Thank you so much experienced elders! Looking forward to standing on your shoulders haha.

Looks like a potassium deficiency to me but I'm no expert. Hopefully others will see this bump and chime in.

Hmm i had thought that myself maybe , either too much CalgMag or not enough Potassium. Appreciate the help! Hopefully others chime in too.
