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.

Calcium deficiency or overfed?Hi.
This is about my Apricot Auto which already suffered the yellow tips/edges. I took that as the result of heat/light stress.
Now she also developed discoloration and brown spots on some of the leaves. It looks like a Calcium deficiency to me, but I am quite uncertain.
Thanks!

They are on the older leaves and they keep getting that faded yellowing starting from the tips. The pH of the run off is 6.43 and they havent been fed a round of nutrients in a week! I thought it was a cal/mag def but they haven't bounced back after a dose. Help please!

Not enough nutrients for Nirvana Maui Waui in light soil?I have overfed my last grow by spraying it with Alg-A-Mic... so this time around I kept giving her only a minimum of nutrients.
Looking at the yellow leaves and the brown spots... most of the leaves touched the tent... am I UNDERfeeding her now?

Yellow leaf on newly germinated seedBlue Dream is already showing a yellow leaf. Was the first to show tap root and all seeds were treated the same and planted in fox forest ocean forest with no added nutrients and watered with Distilled water at 6ph. Not sure if I should be worried now or not.

What could be causing yellow leaves at the bottom of my plants. Deficiency? Are in soil that supposedly has weekly specific nutes baked in. Any helpMost plants in my grow are yellowing at the bottom. One plant in particular is showing what i would call severe stress. I think I figured out that I had an air flow issue causing plants to keel over that was easy to fix. The Bushy one is North shore Maui and the big one is GG.

Light yellowing leavesSome light yellowing on the leaves, more on the smaller nodes towards the middle. Could this be related to my accidental topping, or possibly due to uneven watering? It was very bushy when i tried to water it last, so i am not sure how evenly the soil was saturated.

Yellow/burned tips & curled leavesI have an issue with some yellow/burned tips and curled leaves.
I already suspect that mainly is from light stress but could also be a nutrient deficiency?
I´ve raised the lights the max I can and keep it at 80% for 20 hours.
