Flowering problem

can someone tell me why:
this leaf drooping is happening?
White hairs late in flower?
Leaf tip burn?
I’m in coco/perlite 3gallon fabrics.
A 2x4 tent with led cobs.
Feeding every other day when it’s almost dry.
I’m halfway into week 7 on an “8 week strain”.
There’s 2 banana mangos and a gelato41 in the middle.
im used to doing 10 weeks flower cycles so the gelato seems normal but the banana mango is supposed to be finished in a week and maybe 1/5 of the hairs have turned color.
Just wondering why the hairs won’t turn lol

there is also some leaf tip burn that I can’t get right this round.
And the leaf droop just started and I haven’t done anything differently. Thanks for help or opinions

You don't wait for anything majority coco to dry. Ever. That's potassium deficiency. Watch for nanners from stress. Fresh pistils can just happen. Cut back on nitrogen and see if that slows.

Thanks for responding…I’m giving it advanced nutrients lineup. I’ve read coco absorbs? calmag and locks out the k. Is that what’s happening right here? Would the next feed include more or less calmag? And the pistils aren’t fresh. They’re the same since a few weeks ago they’re just not turning yet and so close to finish?

I’m on week 9 now. Just feeding molasses to leach out some medium salts. Seems it was a calmag lockout, though higher levels of potassium would have helped. Wreaks of mango now
