LED light burn?

[Aarkem]

Good day,
I am just starting out with an LED(fluence spydr x plus). After my clones were about 30 days old I put them into a room with these LED they are approx 3feet from the light itself...but now they all look sick, lighter green, and seem to be wilting?
Water is good no overwater, ph is 6.0-6.2. Room temp varies from. 78.5-81F
Still on younglings nuts, clones are from a mother I've used 5 cycles from already.


Any help would be grand!!

Cheers,
Ark

Looks like a root zone issue. You say they aren't overwatered but they look it.

My second guess would be rootbound, I see you have them in double cups so I'm assuming the inner is clear and you're able to visually inspect the roots. What kind of condition are they in? There's a lot of vegetation there for a solo cup, they may be unable to absorb what they need with such a small root mass. Watering at that high of pH I have to assume your in soil which would also point to the containers being too small.

awesome feedback thanks,
So they are cloned in a homemade aerocloner (neoprene sleeve and plastic netpot) I then transplant them to solo cups. the roots were no bigger then say a single rockwell cube.

Cups inside are slit so i can remove and look at them..none look root bound...though many dont have THAT much soil in the cup. as the plastic and sleeve take up a lot of room....

I am assuming its the light as I have done this quite a number of years without issue until I turned on these lights.

should i take a picture of the roots so you can see if they look healthy/bound?

The light is not likely the root cause though. Those plants have look like they have too much vegetation and not enough root mass for the environment you have them in. They need to be able to drink enough to keep themselves cool. The new light provides more energy than before so they're trying to grow more, which leaves less water for cooling. they need more water to cool themselves down. What's your humidity at? Higher humidity keeps more water in the plant which would be a good thing.

Definitely root bound.

Listen to the above. It's not the light.

really appreciate the feedback everyone. Going to up them into 10gal pots tomorrow(ran out of soil) and see how she goes. thanks for taking the time out!

They are simply hungry feed them and they will be fine.

Whenever you see them curl and dull its from deficiency due to under feeding.And like the little simian said they are root bound solo cup is only good for first 14 days at most then you will run into problems.

Max size for solo cup in my book.

Once you pot them in bigger containers three days later they will have set new roots and will begin to look alot better good luck.

Actually the TOP pic should be about max size for a solo cup IMO.

ahoy I return as I am now into flower and I have a few more questions I thought people may be able to help me identify.

so again it is my first grow under an LED I am using a fluence spydr xplus which is about 20" from my canopy. I have moved it up twice as I thought I was stressing them.

so I have a tiger like stripe on 3 of the 4 plants. which i assumed was magnesium deficiency I started using cal-mag but i have seen no change. all use the same nutes I have used forever, same strains I have grown in soil, dwc, but always under HPS

All of my leaves are so skinny?? I have never seen this before, my brain is telling me that it is because I have so much light the leaves dont need to get as big to process it, my gut is telling me something is wrong.

they bushed out substantially when I put them in 10g pots...but height i never really achieved... I am almost finished week 3 of flower.

light and camera don't play that nice together...rest assure they are quite striped with lime green on those leaves. I want to say as well...plants have always looked sad... i never feel like they are just thriving you know?
