Very near the end of the run, about a week out from harvest

Just want some thoughts on what the hell has happened to the girls on this run?
Just want some thoughts on what the hell has happened to the girls on this run?

Feed: has had a week of GH ripen and now has started flush
PH- 6.5-6.7

need to have an idea of what's caused this to correct on the next run

Plants will naturally begin using the nutrients in their leaves near the end of their life. This is called "senescence". They know they won't need the leaves for much longer, so they utilize the nutrients within them.

It's perfectly normal for the plants to go through this, and is nothing to worry about this late.

By the way, I still see some white hairs there, so I'd give them at least one more week yet before cutting them down.

Dude you need to back off the nitrogen. Your leaves are burned probably because you are driving the nitrogen too hard.

Leaves going into senescence don't go grey like that.

I would have flushed them and fed again. Bit as I say i would bet on you pushing the nitrogen too hard... look how dark green your leaves are

also fading normally starts at the bottom.... nute burn at the top....

Also the buds are a bit foxtaily.... excess N causes this

oh... the solution... Next time when the buds are fully formed but before the calyx fill out drop your base nutrient... down and make the difference up with your booster...

This is how I do it..

Early flower
Base nutes no up to ec. 1.8
Transition
Base nutes 1.6
Pk booster tops it up to 1.9 to 2
Late flower
Base nutes 1.4
Pk boost up to 1.7 to 1.8

Cheers for the comments bro - I have laid off the base nute since I started the PK 9/18 week 4 and was only topping the feed up to EC 1.5-1.7 max with the base after.
It hasn’t been a smooth run this time! The foxtail only seems to be on one strain so I thought I could have been genetics. I thought maybe this was all caused by salt build up in the soil! Do you think this could have been the issue?

Here’s another pic of the issue - this has only come up on one of the strains?? What you reckon this could be - I can’t find anything remotely similar online...

I would say that this strain or pheno woukd need weaker nutes in general... buds look good but there is a mag issue. I thinknits due to overfeeding

Yeh man seem to be struggling doing multiple strains / pheno on the same run - these girls seem to be fussy! Never had this issue before!!

I’m using topic bat mix for medium which is 60% peat and 40% coco with added bat guano and I think that on top of my feed schedule has cooked it a little bit- next run I’m not gonna use the bat shit and I’m going to start regular weekly or 2 weekly flushes to keep the salt build up to a minimum! Fingers crossed for the winter run! Appreciate your thoughts bro

Exactly... that kicks the pH out of range and you are in the lockout. Not so much to do with it in this time, just do not feed it anymore, because it will make it even worse.
