What info would help?Without more info that's might be some big pots for the size of plants. Don't claim to know about cob lighting. But it could also be too much light. Imo everyone might need more info for help
If the new growth doesn’t show the symptoms and the only thing you changed is light distance then it is probably the lights. Did you feed them?
Coco, unchargedThey look small and young. I would never be in a hurry to use nutes. Many plant have dyed from over nuking them. What are you growing in soil , co co ?
I’m using 32 base ppm well water, pHed to around 6.5. ...how much cal mag should I add? Thanks for ur help btwMaybe a little cal mag if in coco or to water
not yet, should I?
I asked because the tips are yellowing which is sometimes a sign of nute burn and i wanted to make sure you are not burning them with too much nutes. No you shouldn’t feed just yet but from what i read coco lacks the required calcium so you may want to add calcium in your prefered method but they are still very small i would wait for the 3rd node at least.
What medium are you in? I don't know how long a seedling will survive without food, but you should always feed coco. Never straight water. For what it's worth. 3 gallon pot for a seedling is hard to pull off.
Yah it’s becoming super hard to pull off...coco won’t evaporate even though I’m only putting in small amounts of water, even though I have above average airflow ... Idk if it’s overwater or underwater ...I haven’t watered these for 2 days and last time only a cup in a circle around it. It’s still damp under the surface, it’s 70 coco/30 perlite. Should I down pot or is it too late...What medium are you in? I don't know how long a seedling will survive without food, but you should always feed coco. Never straight water.

I flushed but no prechargeI would feed 1/4 - 1/2 strength veg food. If you didn't flush or pre charge the coco. I would flush real good with veg food with cal mag. Then play the try not to let it dry out too much while not over feeding and drowning the plants. Waiting for the pot to fill with roots so you can daily feed to runoff.
Nothing to it lol. You will get it.

I agree, I would wait. Looks like nute burn to me. If it was the lights it would be more than just the tips.I asked because the tips are yellowing which is sometimes a sign of nute burn and i wanted to make sure you are not burning them with too much nutes.

It could be nute burn...IF I had used any nutes at that point, but I hadnt. lol.I agree, I would wait. Looks like nute burn to me. If it was the lights it would be more than just the tips.
