Looks to me as if you have a slight N toxicity. You're right around the stage where she doesn't need much N at all so she could be getting burned by leftovers in the soil.
In this case, make sure you've lowered the N in your feed and just keep going as normal until the N level in your soil drops to a proper range. I wouldn't go so far as to flush or anything like that. You may see some more progression for the next week or so before it stops spreading.

The light distance could definitely be your issue if everything else is good. I've found gorilla glue likes a heavy feeding and also lots of light . I had my sf2000 about ten inches or so away . Lower your light by 25% and see what happens. If everything is good . I'd do another 25% a few days later.

Yellow lower leavesGuys/girls please help!
Lower leaves have started getting yellow. I really don't know the issue.
Is it of nitrogen deficiency? A lot of you have told me that 4ml of fish juice is a lot, so is there a possibility of nutrient burn? How can save her?

Yellow leaf tips only on budsYellow leaf tips, only on buds... It is mostly buds nearer top, but some lower as well. It is not happening to fan leaves...
This is an auto, around day 60 (4 weeks of flower). I have stopped giving nutes for over a week already to deal w nute burn. But this yellowing continues!

Droopy leaves, weird spots.Does anyone know what's wrong with that bottom left plant? Those spots appeared pretty soon after I cleaned those filters. I'm thinking that it's a stress caused by that cleanse, no chemicals or such were used, but some roots were torn in the process. Deficiency? Disease?

Lockout or not enough nutrients ?Hi grow fam,
I’m starting to see some slight discolouration on a couple of leaves. I’m wondering if it’s being nutrient deprived or locked out. I am leaning on the side of caution by using GH’s light feed schedule.
No signs of root rot inside the bucket

Correcting some thingsMy buddy is showing some deficiencies, might also indicate not right pH values. Should I wait for the soil to completely dry before correcting the pH or should I flush right away?
Also why does it take 4 days for the soil to dry? I always make sure she drains every time.Leaves. Color - Yellow

Yellowing leavesHey fam,
Just ended 3 weeks of flower for this Banana Purple Punch Auto.
A heap of yellow leaves basically appeared over night.
I fed on the 13th with flower fert (has some N in it) and again on the 18th. This is the only plant that’s going yellow.
What do you think?
