If leaf edges curl up from light intensity, do they un- curl, once light intensity is decreased?

Yea they usually do, when they recover unless they are burned.
Some plants get that tacoing in general tho.

Excess phosphorous will cause tacoeing/canoeing . It's pretty common with all the PK Bloom boosters when Cannabis only need low to moderate dosage of phosphorous in flower for optimal growth.
It all depends on the reason they curl up, if it's from lights stress and low humidity it might be reversible but it's pretty hard to tell what the actual cause is without being at the location.

What were your observations?
My edges on my upper leafs are curling but everything under looks good. Everything is a nice green. I raised my light and turned it down to see if they react.

RH does fluctuate a bit and hanging on the low side.
2 plants in “city picker” SIPs with build a soil blend from my local shop under MH SP3000. Both are Spice Girl fems and separate seeds and BOTH look exactly the same showing the same curling. I had the light pretty close to the top around 16”-18” and light at 40% I’d say. I moved it up to 26” and dimmed way down to see how they respond. My two guesses are either overwatered or the light height.
Don’t mind the netting. Was trying something and shit didn’t come out the way I wanted will prolly have to pull it bc it didn’t hold tight.

I just measure mine out and zip tie the corners to the poles.
