Plant color changing unevenly after trying to correct yellowing.

Both of my Strawberry Shortcakes began to yellow. At first, I though this was a nitro deficiency and applied nutes to combat, but color is changing unevenly. Autoflower week 8, 62-82f, 72-42rh, water in 6.2-7, runoff 6.5-6.6 300-500ppm, double dr earth 4-6-3, ff half dose
Solved
Week 7
Leaves. Color - Yellow

I would personally go more towards an over feed rather than an underfeed and for one reason the lower leves on the plant look fine and if it was nitrogen they would start yellowing at the bottom and head upwards though this is more based at the top of your plant so that would make me lean towards a tad too much of something and that thing would be nitrogen at my best guess autos are notorious for not need much nutrients I haveto put mine on a lite feed scedule to get them to grow properly they can be tricky but overall your doing a great job keep up the great work and well done for not defoliating :) Good going bro im sure she will do you proud at harvest :) šŸ‘Š

The other reason I *think* it might be phosphorus related is because phosphorus is VERY mobile in plants, like it goes from one area to another as the plant sees fit, so when you have a relative deficiency (like even the plant using lots of it), it *might* do stuff like that. But I certainly can't be sure.

Might be calcium, phosphor and sulphur related (especially at that stage) as the phosphor and shit is heavily used then. All of that can be related to yellowing. I'd maybe try bit of epsom salts, some calcium source (calcitic lime tends to be nice for calcium, as it typically has decent sulphur and magnesium too). But yeah, some combo of calcium, magnesium, sulphur. Potentially a bit of citric acid for the medium (as it can help mobilize nutrients). Another less likely possibility, I've had some really strange shit happen a few times due to root damage if I had to guess, like single branches dying completely, shit like that. Cheers, good luck dude.

OP here: the color difference isnā€™t in lower and upper growth. Different branches are turning different colors

I'm not too sure. I have similar things happen sometimes, and I can never quite put my finger on it. Could be stress? Broken stem, too much light, hot spot on that part of the tent, not enough airflow, incorrect ph, that particular bud may have more nutrients needs
