Not sure on the issue, first photos after doing autos for a while

So I have done autos a number of times with zero issues.

Still using foxfarm, same kind of pots, just a different light

I am about a 5 weeks in and going into flower right now.

Leaves were sweating for a while. I think the light was too close and the air circulation was poor so I improved airflow and that seems to have gone away. Getting quite a bit of canoe-ing now but not sure on the issue. Top leaves are folding up. Bottom leaves have some brown/rust spotting.

Some of the lower leaves are looking a bit iffy but I think they are just too far under the canopy for good growth. Not sure how to move forward. I flushed about 1.5 weeks ago, with one watering since. In the beginning I think I was over-watering a little, I was not used to how little heat the LEDs put out.

I added a plain light photo of a lower leaf

what leds are you using and what light have you replaced them for ?

You can get issues with the extra red band some led units have can mean you need more cal/mag

but its hard to tell from your pics could just be over watering or it could be the lower stuff is too far from the light so the plants using it to build top or roots instead..

That clawing looks like it was too wet or the humidity was off maybe ?

Looks overwatered.

over watering

Ill get an humidity meter in there.

I was using CFLs prior to this but I am currently using the Platinum P450 with red band for flowering

Might just be overwatering. I'll let them really dry out before I water next

Overwatering.
