Help please slow growing seedlings

[Bear13]

Hi all,
Please help if possible. Auto seedlings planted a week ago. Germination in paper towels then propagator for three days then planted in buffered coco. Seems to me they are stunted but would like more opinions if possible. Only watered 6.5 ph ec 20 twice with 200 ml. No nutrients yet. Been planted 5 days and seem slow?

They look really healthy and good to me -- and I've had several cups of coffee. You might want to look at @Edinburgh for a model of how to grow autos -- he's forgotten more than most people know about them. Put a sign on your grow room -- LEAVE THE SEEDLINGS alone....LOL

Hi. What are you expecting them to be at 5 days old?

Here's my photoperiods at 10 days old...

And now about 18 days after that...

Patience, grasshopper.

The one with crispy leaf tips is concerning. Were there any nutes in that medium?

Hi yes there were but I flushed the coco to an EC level of 500 before planting the seedlings. I agree it does look a bit burnt.
Here’s the same three today. Not sure what’s going on man….

I've never grown in coco or grown autos, but those leaves should be expanding. I'm not sure what buffered coco is. Sounds like it might be a mixture of coco and some soil materials that give it more cation exchange?

Regardless, it's either because the plant can't get enough water or it is being over watered and the roots are unable to function (and could be rotting). I have read here that it is impossible to over water coco, but perhaps not buffered coco? Cannabis roots need plenty of oxygen. If soil is always wet, it's not getting oxygen.

You also appear to be watering only around the plant. This is not the way to water. Read up on these:

Well found out the issue. I was away and asked the wife to feed them 1ltr of RO water with 0.5 sensi cal as it’s coco. She gave them 5ml so ec was probably around 2700 for that feed. Two survived but slow considering they are 3 weeks old but I’ll push on and see what happens.
Started a blue dream auto (small one in picture) as well no she knows what to feed them
