Seedlings new leaves curling

[Needadvice]

Hi!

I'm a beginner grower and decided to grow some plants of my own just for fun. Looking for some advice from some fellow growers to help me diagnose what's going on with my young curling autoflowering plants. My apologies in advance for the long post!

Question 1

Plant info: Autoflowering strain - Vision Gorilla - Purchased at a smartshop in Amsterdam
Age: 2 weeks (planted 17 may, 2021)
Images: first 3
No nutrients given

I planted this autoflower seed into a large pot into normal universal soil, (soil bought from a flowershop) on the 17th of May. Kept it inside for the first couple of days due to the cold rainy weather we were having here in Amsterdam.

I did have some blue led lights (40 watt) that I kept shining on them as well and it seemed to be doing great and was growing really quickly. Used a spray bottle to spray the soil close to the roots about every 3 days or when I put my finger into the soil and found it to be dry.

The last week the weather has gotten significantly warmer (from 12c to roughly 23c), and since my backyard gets quite a bit of sunlight throughout the day, I moved them outside. In the last week I noticed that the new leaves that have grown, are curling down and the stem was quite thin to the point where I had to keep soil around the stem to prevent it from toppling over. Today, as I slightly moved the plant, the whole plant just toppled over so I decided to re-plant it deeper into the soil - might've completely ruined it, but I didn't know what else to do, hoping it'll survive. The stem was also thinner at the part where the soil surrounded it at the top.

For the last week, they've been getting direct sunlight for roughly 8-9hrs a day, and then I leave them outside throughout the night. Temp drops to about 14c.

I watered it the day before yesterday when it got really hot outside and I used a normal watering can, so definitely gave it more water than I did previously. When Googling 'curling leaves' it gives me a whole list of different causes, and am therefore turning to this forum for some specific advice for my plants!

The reason why I am mainly confused is because the first leaves look quite big and healthy, but the new leaves are curling down. Can anybody pls help me diagnose this?

Question 2

Plant info: Autoflowering strain - Vision Gorilla - Purchased at a smartshop in Amsterdam
Age: 3 weeks (planted 10 may, 2021)

No nutrients given

This one has nothing to do with the above question, however it just looks weird and I'm not sure if it's because it's a mutated seed or if I'm doing something wrong. The leaves are wonky, thin and just funny looking.

Has anyone experienced their weed plant to grow in a similar fashion?

Thanks in advance to anyone willing to help!

Had this same problem with m first grow on here..its look like it could be overwater or underwater. What of pot you using?

Thanks for your response! I'm using a white flowerpot of 35cm tall and 39cm wide - with drainage holes. What did you do with your grow when this happened?

I used to big of a pot for the seedling and once you over-water in a big container your seedling could make it or break it (higher chance of breaking it) . I'll be honest its 50/50 the plants might make it because that container a little big for seedlings would transplant them girls into a standard 8 oz Styrofoam cup or plastic cup. You can keep them in the cups for a good month 2-4 weeks before need to transplant to container. But, during the seedling stage no need to water plant just get a spray bottle and spray the seedling and top of the soil a couple sprays and every 2 days for about 2 weeks this is because the plants haven't formed a good root system and its hard for the plants to uptake water during the first 2 weeks. The plants can drink water through the leaves. Also, your smart on not giving them nutrients as well you mainly want to start feeding them about 4 weeks into growth, reason is the roots are still weak to uptake the extra nutrients but depending on the soil your using most of them come with enough NPK to feed your plant the first 2-4 weeks of life.

Ahh okay, thanks for the advice! I read online that you should plant autoflowers straight into their main pot that you'll harvest from, which is why I planted them in such a big pot.

Would you recommend transplanting it to a smaller pot then? Or should I leave it? I don't want to stress it out too much either.

During the seedling stage rather an auto or photo it's best to start in a small cup for at least the first 2 week than transfer to a gallon to a 3 gallon, most autos will fully grow in a 3 gallon pot anything bigger is too much for the reason being autos don't take long to grow and are small plants than photos. But, as I said once over-watering or sometimes under-watering it could be a 50/50 of the girls surviving. You can try too transplant, if you choose to do so I would use another good fresh batch of soil than using the same its been in but the fact their still young is hard. Me personally I would give it a shot but as I said its a 50/50 chance they will make it but my hopes are high for you!!!

Do you have more seeds to grow?

How is your grow room set up and what soil you using, light and etc.?

Hiya - leave it, it'll be fine once the roots have developed in a week or so
Just be sure to keep the medium damp but not wet
These are surprisingly strong plants if left to do their own thing
Depends how big you want the end plant to be, I grow autos straight into 4.5l pots for 1M plants with no problem
Top a couple of times and you'll get 8-10 fat buds
