Download the app Photone to measure your par from the light. It might not be perfect but it’ll at least let you get a sense of what power/distance the light should be at. Those plants aren’t happy and increasing the light isn’t gonna help that, it’s just gonna speed up whatever issue they have. If the plants were looking leggy with long distance between nodes (from not enough light), sure turn up the light but right now they look fairy tightly stacked.

Are these still under 24 hour lighting??
Yes. 24/7 lighting. UnPH'ed water.

Just going off the par map posted earlier in this thread and what looks like about the 18 inch hanging height you have and that they say to use for veg. ~900 par in the middle - with 24 hour daylight = 77 DLI or daily light integral (aka waaaaay too much for seedlings). Read this article then turn your light down or raise it up within the tent or both and download that app I told you about if you have a compatible phone.
How to Increase "DLI" for Bigger Yields (Daily Light Integral Tips) | Grow Weed Easy
by Nebula Haze What is “DLI” (daily light integral) and how can you increase it for bigger yields? Definition: DLI stands for daily light integral. It describes how much light in the PAR (Photosynthetically Active Radiation) range is delivered within a 24-hour period to an area. “Daily” because...

edit: get a timer and put that light on 18/6. Unless your light levels are dialed in and things are looking healthy there’s no reason to go 24/7 lights on.

Why not go 18/6? Plants do better imo with their rest period.

I'm in agreement with @Satch12 , no reason to increase the light at this time. If anything I would dim and/or raise it significantly.
Light is what makes plants "work," the more light the harder they work. If they are in good health, cool, they'll probably grow a bit faster. But yours are still recovering, no need to make them work harder just yet. If there is too much light they will actually change the shape or orientation of their leaves so they're exposed to less light (pointing down or up, taco'ing, etc).
Imo, in veg the only time you really "need" more light is if they are stretching and have long internode spacing, which definitely does not apply for you.
Agree. The plants were stretching but now seem stocky/stunted.
The plants do feel lighter so they are drying.
- Lowered light power to lowest setting.
- 18/6 beginning at Midnight (off between Midnight and 6:00AM).
-read article and will work on PAR app later w/updates to be posted.
Thanks everyone!

Are you having temp issues? If you are, you may want to have lights off during the warmest part of the day
In the tent temp has been pretty stable between 77.x°F and 79.x°F. RH fluctuates between 40% and 70% right now.
The uninsulated basement temp is 62.x°F and doesn't fluctuate. Technically the basement temp is slowly falling as the frost line goes deeper.
The tent needs a heater. The two controllers discussed should be here Friday. The plants will be chilly for 4 nights.
I did have a cheap oil heater from $WMT but the thermostat didn't seem to work right so it was returned. Now with a controller I'll buy a replacement.

Personally think the 77-79 temp range is totally fine to get them back into good health, you’ll hear suggestions for higher temps with led’s but if the plants are already stressed I think adding in a heater as another variable is just gonna throw things off further. My two cents.
If this is the app, my device isn't compatible with the available version.

I use this connected to my phone via Bluetooth and then use the PPFD METER app from the Google play store.

Oh, wow. I'll have to buy something else. Let me check into this and make sure it's compatible, yada, yada.

I know it's probably not what you want to hear in terms of buy this buy that, but unfortunately you need to get your environment and parameters set up properly. Then I think a lot of your issues will go away. Who's genetics are you running?
