PH Lock, Nute Burn, Nute Def?

Hello everyone, I was wondering if anyone would care to help me figure out might be wrong with plant these leaves came off of. Her name is Mona, she is a baggler*, and she is on her 23 day of flowering. She is growing in coco, and was flushed the night she went 12/12 and again 2 nights ago when I noticed the problem and it was time for a flush anyways. I follow the fox farm soil schedule using half of the recommended strength. I use tap water ph'ed to 6.0, the water sits for three days in a 45 gallon can before I use it. Yes it's clean.

The problem started on the bottom fan leaves, begining with the yellowing and the dropping. Then the brown spots started to appear on the leaves. Last night I removed 3 fan leaves from the bottom that we completely brown and crunchy. It is spreading up Mona but has not yet made it to the newest of her growth. Any ideas thoughts or suggestions?

:peace:

*what I call crap seeds found in random bags. You never know until you grow.

"I followed the foxfarms soil schedule".................<<<are you using soil ferts in straight cocco?? if so yes you will continue to have ph issues which will lock out your major elements NPK.......big problem..........flush and bring cocco medium's ph to 5.8-6.1 and get canna cocco ferts which won't cause a salt build up

Your pics show a calcium/potassium def and a ph issue............good luck

if their is leaf curl potassium def/ not calcium def

I've used cocco and fox farms for the past 3 grows with no problems except for this plant right here. But like I said I use half strength, at least for her she seemed to like it but I also use 1/4 strength. As long as you follow the schedule you won't have problems with it.

I'm pretty sure that she got watered from a wrong jug and got a dose of ferts that were wrong. So I've flushed her again with a weak weak solution of what she should be getting fed right now. I'll keep you all posted.
 
You're in coco and you're using soil food? You should for sure be adding something like a calmag plus. Coco is notoriously selfish with Ca and some soil foots assume that your soil will have Ca as well.

Potassium, Calcium, and Magnesium go hand and hand. They need each other!!!

Roger that, I'll make sure to start adding some kind of Cal/mag to my water.

Is it odd to use FF in coco? The instructions in the brochure say it's fine just to make sure and do a good flush since they retain salts more than peat based soilless mixes. Like I said I don't use full strength I flush whenever the schedule tells me to flush. I hand water all my girls. I feed them every 3rd watering, and I water them till they drain whether I use plain water or nute water. Fox farms are good nutes if you follow the directions.
