20 day old stunted seedlings ??

[Gman420guy]

These seedlings are both close to 19 days of life since sprouting.

It’s hard not to compare their growth progress to some of the other explosive grows I’ve seen with the same strain.
It’s tangerine dream autoflower from growers choice.

I’ve tried recently keeping them in a humidity done. Close to 4 days now while allowing a few hours of fresh air per 24 hours. and they seem to be making very slow progress.

I had a male auto show much faster growth within the same conditions inside the tent without a dome.

67-80 F average
45-60 RH

Very Light misting in the morning. Then root watered a few squirts from a bottle ph 6.3 aquarium water every few days.

They appear healthy. Maybe some slight reverse canoeing of the leaves in the smaller one. Meaning it’s shaped as an upside down canoe, but very minimal. This really only becomes noticeable when I remove the dome.

I’ve raised the tents humidity to 50-60 RH and temps are 70-80 now.
I suspect stunted growth from RH or temp.
Live soil , added bigger perlite , very small amounts of slow release amendments, bat guano , oyster shell, and Gaia green vegetative blend.

How do I help these children.

Thinking about adding some (airstoned) lol , and black molasses treated water to some feedings ? Microbial problems possibly?

Ditch the dome.........domes are for clones..........not seedlings.

it’s been off for a few days now. I’m seeing growth , but it’s still painfully slow

Duh. Huge container. Tiny plant sending roots out. Be patient. Don’t overwater.

Part of the problem is the size pot that it's in.
Some people will disagree, but I find it very challenging to maintain the proper moisture level in the soil with a small seedling in a large pot for fast growth.
I prefer to start in smaller containers and transplant.
18 days from sprout for a comparison.

PS......autos don't need to be started in the final pot.........it's a stoner myth.

I dont understand the apprehension alot of people have with repotting photo's or auto's.
I score my rootballs at repotting and the plants dont seem to notice or slow at all.

with the limited veg cycle of autos is it worth being patient at this point with so much time wasted ?

I did a metric shit ton of research before starting out , and the majority of info I’ve seen across the board points too starting in the final. It makes sense limiting stress . But I seem ti have fucked myself by cutting my veg time in half if not more.

Mick is right, I've always seen faster growth in my plants that started in small pots, and were potted up twice. You get better root growth doing it that way.

I, too, learned the hard way about this. However I also discovered that time claim by breeders can be bullshit. I had 2 autos this year that ran for 3 months before almost finishing. Snow took them out last week. Just be patient.

Just because it's repeated over and over that autos should be started in their final pots that doesn't make it correct.

I transplant all my autos from starter pots to their final 3 gallon containers. They love it.

You're overwatering. Stop misting your plants and stop using the dome. Your issue is 110% not the RH or temp.

What sizes did you start and put up too ?
