Hi guys, first time posting here and first time grower.
I have a few Northern Lights Autoflower and a few photo periods, Skunk#1 and few unknown strains. All my autoflowering plant leaves are starting to curl up quite badly with some curl on the photo period plants. The photo period plants are a week older and were under a crappy light for the first four days of their lives.
Setup:
600w Dual spectrum HPS.
75% 3 week fertilized soil 25% perlite. No added nutes currently.
18/6 light cycle.
Watered every 2-3 days.
Temps are a tad high at times 80-85f.
Humidity is killing me. Struggle to get higher than 40% when lights on (thinking this could be the issue).
Here's a few of the NL...

As you can see starting to curl up pretty bad.
Here's a PP plant in the same pots..

Some curl but not too bad.
Here's the whole setup..

My thoughts....
Heat: It looks to me that the pots that are less filled with soil are creating some sort of heat trap as ones that are more filled show less signs of curling. You can see a few more photo period plants there in smaller pots that seem to be doing OK. That don't seemed to have the same problem.
Humidity: Is the low humidity (probably coupled with the high heat) to blame?
Does anyone have any suggestions of what it could be?
