Ive been moving the light up n up lately as the plants have grown quite a bit in the last couple weeks…right now maybe 10-12 inches…just moved it to that today tho…the tops had been getting probs within 6-8 inches
That close can be an issue.
Im running out of room to move up lol…anything i can do to stop the upward growth?
Yes supper crop.
Also I will tag some people with more experience and knowledge to help pin point what’s going on.
To help them though fill this out as it will help them get an answer quickly to you.

Always try to upload a clear picture in white light of any issues you may have to allow the community to assist you.
I’ve been looking at this, first can you get a picture without the grow lights. Either with some type white light or flash from camara. The leaves are canoeing can’t tell but it looks like the fan leaves are also extremely dark green. I’m also seeing some leaf tips burned. Could be heat related and nutrient related. So going to need some good pics and support Ticket info.

Are they autos, even if they are I don’t believe need 19 hours of light.
Did you ever feel if the plastic was hot or warmer to the touch? If not then the heater probably wasn’t doing anything bad.
Need that picture if possible, in natural light. I don’t see that you have any ppm runoff reading. Also I don’t see if you are using any nutrients.
They are autos…i asked bout light scheduling a few weeks ago and consensus was to leave em at this sched since they were autos
I just checked them and didnt notice anything crazy…but heater is in an off period
Roots can get warm and be fine, constant high temp or root temp higher than the plants leaves is when there would be concern. Still good not to have heat directly blowing on them though. 
, but from the sounds of things temp and humidity are lower on the concerns.
Like Bulldog said, knowing some PPM’s and any nutrients they have been getting will help.
Bigger pictures look good. Look like they have enough nitrogen, the darker green leaves.
Sounding like i need to get some nutrients to them!…so ppm being different than ph…this is my first grow, whats best way to figure?
The bottom leaves dont have the issue the same
Not saying they need nutrients. I see that they don’t need any nitrogen right now. I’d wait for others to chime in on this but, MPK is what they look for in flower. But knowing what your PPM’s are coming out would help to know if they are wanting food.
How do i figure ppms?
TDS or EC meter.
