Is my auto stunted or does this look normal for a 12day old seedling?

Markyb · Jan 21, 2025

Hi!
First time grower. I was wondering if my auto should be bigger at this point?
I do see growth every day, but a friend told me it should already be much bigger at this point.

Another thing I found interesting was the aroma, today I noticed the plant already gives a mild aroma when I bring my nose very close to the leaves.
The aroma is very pleasant, like a mix of citrus and pineapple. :)

Setup:
Lights: 100W LED, set to 61cm (24") and 60% PWM
Pot: 10L(~3Gal) smartpot
Medium: Biobizz Lightmix with extra 30% perlite added
Temp/RH: constant 25C (77F) / 70%

Looks alright to me! This was one of mine at 12 days

Well... I've only grown a few autos, but I have two Royal Creamatic from RQS flowering right now. They grew so slowly at first that we were talking about pulling them and starting something else. Then they just took off and grew quite well. The light is rated at 240W and is running at 67%. I'm using organic nutrients.

I have a few thoughts about yours. I don't know if it should be bigger, but it looks healthy, so I'd increase the light every few days, while watching for light stress. If you see stress, back off the light a little. You can probably get it up to 100% by the time it's flowering. I would also reduce the humidity slowly till it gets to about 55%. That will increase the transpiration rate. I don't know much about Biobizz, but I understand more organic nutrients can help eventually.

Boibizz light mix is just peat with minimum nutrients it lasts a few weeks mind before you need to feed it.

I use it myself albeit I don’t use the light mix unless there out of the normal bio bizz soil it’s nothing special but does what you need it to do.

Yeah looks healthy enough
100w will only get you through veg mind if there’s two plants
Even just one plant would prefer more watts during flower in veg fine no problem a 100w would suffice

Watering will be the biggest issue as to growth at this point to much & they slow down & with autos you need growth to be optimal
If the soil feels moist when you stick a finger in it it’s probably good for another day.

Haha if you can smell the different aromas wait till it starts flowering

Thank you everyone for excellent advice!
I will increase the light little bit today and see how it goes and start gradually lowering the RH. Thanks!

it will pause for a bit because its using its energy to put some roots down...leave it alone for the next couple of weeks... i personally at this stage mist them with diluted root juice , i think it just gives the roots a boost .

Also, I noticed this morning that the poor thing was looking a little bit sad, leaves a bit droopy and it was leaning a little bit. I think I have been starving it from water..

The very top layer (½" or so) was bone dry but under that the soil felt still somewhat moist. But weighting the pot indicated that there were barely any water left. It weighted only a little more than the dry reference pot I have, even though the soil felt moist.

After watering, it perked up fast and after few hours it looks much happier now.

After germ a plant will produce a node every four days in acceptable growing conditions. Because of low light conditions, your seedling released a hormone that causes rapid stem cell elongation in an effort to reach the light it requires. This happens at the cost of root and node development so it's behind a few days. Build up medium to within 1/2" of the cots for support, provide adequate light (300-500ppfd 30-40dli) provide air circulation to strengthen plant and bring Rh down to 40-60%. Post another pic in 12 days and you'll have five full nodes. Good growing to you.

Congrats! Your first lesson in reading a plant! I think they’re on track! Good luck!

Thanks everyone for your advice!

Here she is today, day 20. Grown quite a bit but still little behind I think.
I'm kind off worried about those drooping leaves, the other leaves are just fine but one of those big leaves and the first serrated leaves just keeps drooping. Those leaves are in the shadow mostly, could that be the cause or is this something that naturally happens to the first serrated leaves? (Even the cotyledons are still there and show no sign of falling off).

I fed her the first time three days ago with 1/4th of the dose the fertilizer manufacturer recommends.

Also I have slowly brough down the RH to around 50% and temperatures are around 26-26.5C when light are on, and around 22-23C when lights off.
And gradually increased the lights to around 23 DLI and slowly going up. (I had to dial down a little because the leaves were starting to get little pale at some point)

I would remove the 2 5leaf fan leaves blocking your lower nodes from light,
will help the undergrowth catch up giving you more budsights come flower

NairnM16 · Jan 29, 2025

If u don’t wanna cut anything u can also use a plant tie nd bent your stem off to one side then work clock wise round the pot you’ll end up with a wee shrub looking thing with only tops rather than the traditional Christmas tree look with the main cola

Markyb · Jan 29, 2025

Thanks! I will think about it, the two 5leaf fan leaves are quite large and really block the new leaves growing underside of it.
Damn, I'm just really scared of cutting anything off, its my first plant an all. :D

NairnM16 · Jan 29, 2025

Seed to stoned on YouTube does verry good autoflower runs I personally like to train my plants so I stay away from autoflowers as you look at them funny and the go wrong
But if u do it right u shouldn’t have any problems just stay away from high stress techniques

Oldchucky · Jan 29, 2025

Fuck it! Grow them out, but start some new autos anyway! They can all be growing under the same light!

Is my auto stunted or does this look normal for a 12day old seedling?
