DWC stunted and yellowing. Why no growth? :(

OP has the plant in a cloning plug....and that is it...nothing is in the net pot. Not sure if that is a thing people do.

Had to have the seed in something to germinate it no?

It is.

I germinated the seed in the cloning collar. No rockwool cube. No plugs. Nothing. It works. (Or dosent). I do not know if the plant problem is related to the lack of medium.

also what is the water level to the net pot?

The water level is below the netpot. The bubbles made by the airpump let the roots and the bottom of the cloning collar wet. The roots are in touch with the reservoir.

Thanks for all replies. I think I will lower the light, see how it goes. Change the water to tap ph'ed if no improvements. Maybe it's just better to start over.

If the green doesn't start to come back. I would just start over. It can be hard to tell if a seedling is struggling. But it should noticeably grow every day.

Let us know how it looks in 2 days.

That little plant is in a tent with led lighting, and the air temp is 70F? Do you have an IR thermometer.
That's probably *way* too cold.

It affects growth but not to that degree I think? 21C/70F should be fine for veg in hydro. You would have a harder time in soil though with that low temps, especially running LED's. It's a weed after all.

Ph 5.8 calibrated pen. 3.2 ft from lamp. I use a luxmeter 15.000 lux.

Way to much light for that size of a plant. I think we put the last nail in the coffin. Cheers!

If the roots are growing theirs hope yet

I disagree, respectfully. That cold temp is also going to affect other stuff, relating to metabolism, etc. There might be other issues. But honestly, I'm surprised nobody else noticed or mentioned that that temp is way to cold. If it were under hid, the plants would probably be around 75F+. But now, it's definitely under 70F. *The plant*.

@Urso hidro Get yourself an IR thermometer, if you don't already have one. You won't regret the $20 it costs (or $6.00 USD) .

Edit: also, OP, try the PAR/LUX meter app in my signature. iOS or Android. Free at the moment. Compare the lux reading from the app to the one from your lux meter - if you want, I mean. I'm curious.

IR thermometer on leaves 72F. I reduced the light to 8.000 lux.
