Hey so do to some issues I put one of my autos under 12/12 has been for about 6 weeks can I jump it back up to 18/6 or move it up gradually? Probably 3-4 wks to harvest.
I don’t see why not, but I’d wait and get a couple more opinions.
Should not be an issue to switch all at once.
Is the auto flowering? If so, just be alert for signs of stress like nanners.
Nanners are a type of male flower that can appear in late flower as a result of stress. They pop out of the bud and are usually a yellowish color so they stand out.
Here is a close up shot and you can see where they get the name.
I tend to agree with that plan for 18/6.
My experience of 12/12 to 24/0, got 30 % femaled nanners contributing greatly to the 2022 Summer Orgy at my place. Fall seed mining has been fun, almost like watching the snow melt. I place two LST benders on two of my summer seed orphans, today, after re-potting four of their siblings.
Those things herm easily enough, I would leave it be.
