Hi, I repotted seedlings 3 days ago, yesterday I noticed these spots appearing and the leaves slightly turned down, any suggestions as there not being over watered, I’ve not started using newts yet as they are only 2 weeks old and the lights are far enough away. The humidity could be better but I can’t think of anything else as the cause.
There on 18/6, 600w led, indoor, temp 24/25 degrees, potted in coco.
Thanks

The roots was all round at the bottom of the solo cups quite a lot of roots so thought it was time? I will lay off the water see if it makes a difference as they’ve only been watered once in 4 days. Lights are 35 inches away. Thank you for your help

Three weeks is too long in my opinion to go without nutrition. Coco is inert. New seeds can go for a few days, maybe even a week, without anything other than what they have on board. After that, though, they start getting hungry. I pop my seeds in a root riot cube. As soon as they are up, I get them in a cup of coco and start feeding daily on that day. Remember, coco looks like soil, but it’s really hydro. If you went three weeks running your hydro plants on just water, they would be seriously pissed.

I did exactly that apart from add nutes, I gave them water last night should I let them dry out and next water add nutes or would they be too long, thanks for the help.

Coco does not like to be dry cycled like soil. Small veggers like that at my place get fed to runoff once a day every day. Drying out coco causes it to do all kinds of bullshit you don’t want. PH swings and salt accumulation primarily. If it were me, I would feed them as soon as you are able. No need to wait imo. Just don’t hammer her too hard. It’s way easier to add more in her next feed than to get her adjusted back from over feeding.

So in your opinion there not overwatered either? I’ve read it’s pretty much impossible to overwater coco with perlite mixed what’s your opinion on that?

Correct. You can definitely have a ton of problems in coco, but overwatering not generally one of them. you can overwater a small plant in a really big pot. Even that is pretty tricky though. Once my veggers get some size on them, they get fed at at least twice a day and I will give them a third if it is hungry strain.
This gal is in veg and just got fed. She will get fed again around noon and then again at about six. I think of coco like a store shelf. My job is to keep it stocked with fresh full-strength nutrients at the correct ph. The coco literally just holds her up and holds liquid nutes. If you have your nutrients perfectly dialed to what she is eating, you can basically feed her as many times as you want. Your biggest risk will be throwing away a bunch of nutrients you didn’t have to. You won’t hurt her though.

What size is the pot you have her in currently? If the pot is a little oversized, I’ll show you a quick trick that will help you get your feeding dialed in until she gets big enough.

Yes I have put them in quite big pots as didn’t want to transplant again they are currently in 20L pots and so far I have only watered around the edge of the seedling being sceptical about them being in larger pots and being so young still.
Can’t believe 3 times a day maybe that’s where I’ve been going wrong I’ve been so scared of overwatering symptoms that I’ve never fed that much.

Three times a day is a big plants thing. She’s not there yet. Once a day for her. This is what I will suggest to keep you from overwatering her. Cut the top 2 inches off a big solo cup, or other similar sized container. Put the “cuff” over the plant and push the bottom edge just into the coco. When you feed for now, pour your feed inside the solo cup. Feed it until runoff once a day. Once the edges of the canopy get comfortably past the edge of the solo cup, you can still use it as a guide and water around the outside of it. When the canopy reaches the edge of the pot, pull up the cuff, cut it off and water the whole pot. No dry spots. Coco plants shoot out roots fast. Even when they are small, water to runoff so they can grow to the bottom of the container quickly.

Ah should be no problem then. I had a similar issue with my plant (although much further ahead) but it was a combo of overwatering + light too close.

Mine is in a soil, coco, perlite mix though and I was defo overwatering

Cut it down to about half to 1/3 that size and flip it over so it looks a little more like a funnel. You got the basic idea though. When you pour your feed into there, it will focus it into where your roots are growing. The feed will spread out like an upside down cone through the media. Your roots will follow it.

Once you add soil to the coco party, it’s a different party. Then it’s amended soil and you should dry-cycle it like soil.
