Hi everyone. I’m rocking a new set up and I transplanted some nice clones the other day but a few of them seem to be suffering a bit. I’m not sure if it’s heat and/or light stress, a little bit of nutrient burn from the new home, maybe low humidity stress with low ambient temp and high direct heat and light...fuck I dunno, there have been a lot of big swings in range..any help would be greatly appreciated.

Running 2 1000w MH @110% - 5 feet from canopy
Leaf temp 67f was 80f the other day
Ambient temp of 67f-74f
Humidity sitting in the 20% range, real low
Growing in sunshine mix soil

Sunshine mix doesn't provide any nutrient value to speak of so you have to feed with some sort of nutrients. I find the ideal pH is 6.5 - 6.8 for me. Testing the pH of your soil would likely reveal that it's high. When I used sunshine they changed peat moss suppliers and the pH went way up, stopped using it.
 
Start feeding them a good veg feed with calmag (RO) at 2.0 EC and pH of 6.5 - 6.8 and they should respond well unless the pH of the sunshine is way off.

Damn I chose the sunshine mix because I thought it would be sufficient to supply nutes while the delicate roots get settled. I popped some orange chemo in the mix and just watered for a couple weeks and they went better than fine, but these clones are looking sad, so I was confused. I’ll try a light nutrient mix and some power thrive and see how they look :weed:
 
Those are definitely starving, also I’d wet more of the soil when you feed too. Also not sure why you’d be running the lights at such a high intensity right now? I’d be running them at 400w with the light way closer to the plants.
 
Were these clones taken off a flowering plant? Pic # 6 looks like it has amber pistils on it. Aside from them not having any feed, this may be playing a role in them getting going. Or my eyes and glasses just suck...it's possible.
