I am growing 4 plants. They are auto-flower 12 weeks old. They have all started to show signs of distress. I think it’s a problem with nutrients, but I can’t identify the problem. Any ideas?
I uploaded pics, do they show here?
Welcome to the forum.
I use the same fertilizer line. It may be nute burn. Do you know your runoff PPM?

Hey @Fred35, Welcome to the forum.
Many others will chime in soon.
My question is , Did you do the scheduled flushes?
That all looks reasonable.
She looks overfed to me. Too much nutrients, or a salt buildup in the soil. Spiney asked a good question. Flushes will always be necessary if you are feeding (even as per the FF schedule.)
Thanks for the responses. Two of these plants are about 3 weeks from harvest. Would it be ok to do a minor flush now? If so, should I add nutrients back in? Then a final flush in a couple of weeks?
Or should I just perform the final flush on them now?
Yes I would if you havent been… right now salt buildup will cause issues in ph swings and more or less food won’t effect it … to much of something can block other elements and ■■■■ versa …somethings of that nature will cause excess if an element and cause ph to swing to which in turns won’t allow certain elements to be absorbed in turn will cause build up as well
That kind of leaf damage is common in late flowering. Flushing certainly won’t hurt.
Moving forward adding cal-mag to your feedings is usually beneficial. It can help minimize this kind of damage in late flower.
To me looks like a late flower calcium deficency but mast cal mag supplements and manufacture feeding schedules call to cut cal mag at week 6 of 8 week flowering plants…week 7 is a last boost week without calmag and week 8 calls for a seedling level base nute feed
