Deficiencies or light/heat stress?

Hey everyone I’m a little worried my gorilla glue auto might be under stress. A couple days a go temp went up to 85 degrees for a day and had it at only 59% humidity. Raised humidity the next day to target relative humidity. Noticed brown edges with leafs turning slightly yellow as you can see in the pictures. And orange/yellow spots on some. Now I have it at 82 temp 70 humidity. Also seems droopy. Had 100w true watt led at 18 in. Today I raised it to 20 in to see if that helps. You can see two big unhealthy leafs in the pics. any suggestions are much appreciated. Thanks
Growing In super soil(living soil)
Bent her at the end of week 3
Now is at 31 days(4 weeks)
Only have removed a total of 5 leafs since week 3. One to promote light to lower branches and four bc of brown edges and were turning yellow.

Looks like you got a magnesium deficiency on those larger leaves

Completely agree.

More information would help.

Thanks! I’m about to add some Epsom salt
