Leaf burn after flush

So week 7/8 flower I flushed the tent plants were fine 3 days after I gave them a light water ph6.5 24 hours later couple have yellowing on the sugar leafs on the buds. First time I’ve Ever flushed plants. Last few harvest When i started using GH flora Nutes I was absent for.

Yellowing leaves aren't "leaf burn". They are turning yellow because the soil has been depleated of nutrients and the plant is pulling what it needs from those leaves. That said, there really is no reason to flush plants before harvest, unless you are just trying to save money by using less nutrients.

I’m trying to load a couple pics

No they needed the flush took almost 6 gals of water to bring the ppm down into the 500 -400 range

Per plant, it just doesn’t look like it’s leaching/ fading more like burning

It might just be fading, I just have never had yellow the sugar leafs didn’t think it was a good thing. There gonna be cut down soon this week or so I do t wanna give them anything extra

Running that much water through the roots you shocked them, and possibly locked them out. That plant needs more then a week still probably 2-3 from what I can see in those pictures. It still needs to finish swelling internally and ripen.

Let it dry well before watering again, and then just continue with plan water u til it’s actually done.
