Did i mess up the nutes or is this a normal fade to finish.

20220511_065544.jpg20220511_065554.jpg20220511_222304.jpgthis is a pre 96 og kush, at around 55 days flower. Based on trichs and pistils it looks like it still has 3+ weeks to go. This pic is from 2 days ago when I looked last night it was even more faded yellow. Maybe the end is closer than I thought. Feeding advanced nutes ph perfect. Temps80 day / 72 night 55 rh. Led. Soil promix hp

There's no such thing as end fade. If a plant is turning yellow there's an underlying issue
Judging by the curled crispy leaves even on the green plant I'm gona say you're feeding too much causing a problem in your medium. I bet your runoff would be ultra high ec. When this happens the ph changes and the medium begins to 'lockout' other nutrients causing an even bigger buildup. It's hard to say what exactly is the issue without knowing your feed schedule and some more info.

Yep. Looks like a few things going on in this tent. There's some environmental stress (see those curled, canoeing leaves)...I'd guess heat or too much airflow. There's been some overfeed & nitrogen heavy feeding (that back plant is really dark, tips are burnt), and the yellowing is something in the P/K part of the equation possibly locked out from the overfeed, etc.

From the look of those pistils, the plants have some weeks to go, so 'end of life fade' is probably not happening here, though most likely wouldn't happen in general if people didn't flush and starve their plants.

No flushing over here, I have been feed every other bumped it back to almost every three waters. I water every two days so usually water then next feed is with advanced ph perfect at what is recommended, I'm guessing that's still to much then. By the looks of the buds I still have until june

The curled leaves look to be because of high ec and low humidity. I'm kinda shot in the dark-ing here a bit. So you water twice then feed full strength? Hm why not just water/feed at a lower EC to runoff every event? Having a TDS meter helps. Are you using the whole kit and kaboodle an line? That could be another factor too.

Plants that need more phosphorus than soil pH allows often get red leaves.

It's really tough to correct things in promix late in flower without potentially causing more issues. Coco, little easier. Without having the proper instruments to measure the mediums pH, runoff ec, it's hard to give you a direct 100% answer either way. If I were to guess it's overfeeding on feeding events.
The curled up leaves and burnt tips indicate that.

I kinda of thought it was over feeding but a guy at work said not to worry about it. I dont have a tds and I usually don't water to run off either, just kind of soak the pot. I have noticed I have had problem with autos especially outdoors in big pots. I just use the 3 part ph perfect by advanced. Maybe I should back off on the amounts? I was feeding earlier every water but was going through too much fertilizer and seemed unnecessary but I stopped that before flower.

I'd start around half strength and go from there. Right now, you likely have a buildup so removing that buildup is first step. Like I said in promix it's a bit harder late flower... You don't want to swamp the pot but you need to clear out the bad. Do you ph your feed and water ? That could be another thing sending in diff ph water all the time can cause issues too.

The advanced ph perfect seemed to be working I would add the nutes to the water and check with the test kit and would show around 6.5 or lower so I'm assuming that my soil is loaded. I am not flushing but trying to water to runoff slightly to help it out. Might do that twice. Then water. Should I cut out the veggies nutes from the lineup?

Ya a lower ec feed might help... Sorry what do you mean veggies nutes?

Yeah I didn't know that, I have been told by growing buddies that's that's normal. I figured as it reached its life span leaves would die off

Yeah, but that's because so many people have bought into 'flushing' at finish. Of course if you starve a plant for a week or two it's gonna start cannibalizing its own leaves. Though you can't 'flush' any nutrients out of plants once they've taken up the what they want through osmosis, it's a one-way street.
