Ok I may be tripping out alittle but I feel like I may need Some help. What do I do with these curved leaves and what is the light yellow spot? I just fed with a dose of calmag and they seem to be doing better but I'm worried about the curved leaves mostly. Here are my specs. Also what about the thin stems?

Soil, Canna Coco

Strain- Auto- Pounder

Age- 2 weeks 5 days

3 pound cloth pot

Gaia green 4-4-4 to start and at 2 weeks
2-8-4 top fed

Dechlorinated and Airated tap

48-60% RH

81°

4 MIGRO 100 COB LEDs

Co2 5 after the hour every hour for 10 minutes

15 SCFH

Thanks!

I had similar issues before and it was the beginning of a calcium deficiency. Are you using cal-mag at all?

Overfeeding can cause similar issues as well. On top of what Boog said with light or heat stress.
 
Coco can be a cal mag hog, most cocos will lock it up making it unavailable till a saturation point is reached. It's an every feed thing, from the start. Twisted growth can be a sign of calcium deficiency. Which would fit given your question suggests that you just started to give cal/mag.

LED lighting can make cal/mag needs increase as well.
 
How far away are your lights? Thats a good amount of light on seedlings so just wondering. The yellow spot looks like possible nutrient splash from watering?
The lights are 14" away dimmed to about 60% I started the lights about 3 ft away and moved them closer after 10 days. The splashing! Yeah I believe that's what that is I got some on this one especially.. and how long should I consider these things seedlings? This is my first Auto run.. I'm working with Coco and slow release nutes for the first time as well.. lol used to aeroponics but my room is attic bound so humidity is a factor I wanted to avoid until winter.

Good shit bruddah, I had a hunch it was the cal.. I JUST intro'd calmag but was clueless to the Coco combo. Should I be worried of over watering if I'm looking for a saturation point?

I just started calmag but am new to Coco as well as autos and feeding.. I'm hoping it's not over feeding.. I did put an extra scoop of 4-4-4 after realizing the parts were changed by the producer but the others are doing fine from what I can tell other than a bit of stretching from my lights starting pretty high.

I'm going to add here, I just saw your in coco, but looks like your your using soil amendments. This makes for a rough issue as pH is addressed differently in each. If your following a style of a particular grower, best to ask someone growing that way.
Cocos great advantage is the ability to push cannabis hard, like hydro. Issues arise and you flush the medium clean and reset to correct values. And is almost impossible to overwater.

Soil is an amend and wait medium. As your waiting for things to break down to feed the plant. And supplementing a little extra. And soil holds water longer, reducing feedings, But easier to get overwatered.

PH of each is at a different level, diagnosis becomes much more of an issue.


Will keep looking in.

Also, CO2 will increase the need for nutrition, if your looking for an increase in size and yield, appropriate feed levels will need to be looked for. Cal/mg use increases as well.
 
I would back away the lights to 24 inches. @Arthur might have a better idea of 4 cobs at 60 percent power.
That's what I was thinking. The manufacturer who made the cobs recommends 14 to start. But I will move them up a little.
