If you have the light up that high, and had the tent working with HID, then it's almost certainly not intensity or heat.

How far along are you?

Those pics are certainly more than 3 days in, and look somewhat like the fade that happens late flower if food starts to run low and the plant is finishing up. If that is happening too early, then it's probably a feed issue.
prolly lack of heat since the light is so far away and doesn't create near the same leaf temp as HID at the same ambient temp. Move light 20-24" off canopy and let temps reach 80-82 should perk up.
 
HLG 600 finally landed today.
got 2 autos under them plus other crops.
About 2 hours later at 40” at lowest power.
Babies are praying (:

hopefully you narrow down your issue.

if growing cannabis is that scientific, I’m screwed. So hopefully not.

I’m in so cal. I was using a humidifier it found just by watering the plants was raising my RH levels to target range
Science? Nah, sometimes I feel like a scientist but it's like growing weeds.. I've had sunflowers and tomatoes and even a palo verda sapling in my tent.. i have made many many huge mistakes, these ladies forgive easily as long as you notice the problem and fix it:weed:

I would try like mentioned and get the temps mid 80s or where they seem to do better with the hid and try the led again, I don’t do led so I have no idea how much a few degrees can affect them, I assume not that much. The guy on your lawn knows more about that :lol:

I skimmed threw but didn’t see your feed strength are you using a chart or off the bottle?

J232 I think ur correct about raising the temps using the led. My only choice to raise the temp would be to turn the light up. But being they looked stressed and are only a few weeks old I didn’t want to blast them with full power of this light

As far as I know, you can supplement heat if required with led, maybe a small space heater? Doug would know about the risk of full power, maybe at a high enough distance it would be ok, I would go the space heater route myself. You could also raise the temp in the room the area draws air from. Too cold isn’t in my grow vocabulary lol..
