Hi all

I'm at the end of flower in my first grow and one of my two plants is starting to show some problem signs so I'm seeking guidance.

This plant was planted September 25, 2025 and flipped to flower Dec 1, 2025. It's an Amnesia Fast photo strain from Seedsman.  it's being grown in a half mix of foxfarm happy frog and ocean and ive been using a foxfarm nutrient set - thr grow big, big bloom, and tiger buds.  I balance the water pH and so far the grow has been uneventful and smooth.

everything has been going well until about 10 days ago when the plant's leaves stared drying out and their tips curling in.  theyre so dry I can pinch them and they crumble to pieces. ive been trimming the leaves most affected and pinching off the dry bits forming daily while I tried adjusting watering and nutrients to find a solution, but now it's starting to affect the areas sticky with trichomes which makes that harder to do and means im just losing bud now.  ive included a photo where I hope you can see the trichomes, which still seem largely clear with some cloudy? it doesnt seem ready for harvest and the other plant in the tent still has largely white pistils and what seems like a long way to go but im also worried that the drying leaves means it's stopped drinking and it's time to harvest before ive waited too long and ruined my crop?  can this be solved?

any guidance or input is appreciated! thanks!

Need help understanding what's going on at very end of flower phase with drying leaves
