Distance from the lamp to the plant is 20-25 cm. Do not go far, start from the edges so that the roots look for water. Do not forget to blow out plants😂

Light is a bit far from Plant It Happened to myself i moved to around 5inch away and did the trick. Dont Have to much air going around as well as that can be a pain with Humidity. I did see you have your light schedule to 12 hrs. I really hope you not giving them just 12hour light at this stage should be 18/6 to 24hours.

Hey I had a similar problem, stretching. I too used a conventional clip lamp with some cfl bulbs...the beauty with those is they can be kept very close, 2 to 4 inches. I think using the makeshift humidity dome and making sure the lights are fairly close should give you some new growth over the next week or so. I hope it all works out, the window lighting is great if its getting some solid direct hours of light, it'll make a good difference. Also seedlings love warm and moist, I put a little space heater in mine just to keep things up in the 70's Good luck and happy growing!

Looking good so far, always remember, less is more! Especially at this stage! Ive burnt many a seedling wanting to make it grow to its fullest potential lol. If the stem is stretching then it def. Means to put the light closer. I start with 1 or 2 decent size CFL lights and just give them water.. If anything, a half dose of bioroot. I put them lights literally an inch or 2 above my plants until they big enough to go under the HID light. Looks good tho, just keep doing you.

I agree with the 14 people who said move the light a bit closer, but also curious if your in soil or coco? Young roots can cruise thru coco quicker than a thick wet soil. After you water let the medium dry up nicely so the roots reach down for food and it will likely grow a little more rapidly. Also, seedlings prefer a slightly more acidic ph, but depending on what your dirt is it varies, 5.6 - 5.7 in coco works for me and if your in soil 6.1 - 6.2ish should be good but double check that I'm not a soil guy. Temp and humidity being out of wack can also hinder growth as well so for optimal growth it has to be dialed in and consistent, dont create too much wind in your space either. Hope this helps friend best of luck! P.S. keep root zone warm but not too warm, too warm with acidic ph increases chances of fungus mold and mildew (root rot).

Lower the distance between your light and your plants, and when repotting, put 1-2cm of stem under the ground. I'll be around, good luck with this baby bro!

Simple and easy yo spot this one. You plant is stretching to reach light. Specially on regular strain be careful if you have a small space to grow.

Looks like its stretching for light. Id put the light closer, depending on what light you're using, use your hand to test the light distance and heat. If its too hot for your hand, its too hot for your plants. - This would mean to raise the light a little more till you find the happy medium. Also a small fan blowing over your plants from a distance will help strengthen and thicken up stems in time. Maybe try invest in some bamboo type stick for support next to your plant, guaranteed to help.

Looks like its stretching big time,i usually have a flo fixture 12-18 inchs away from the planfs. You can add more medium to keep it from falling down. Seedlings dont need water sprayed every few hours, the small amount of heat from the light should be good enough. If not add a seedling heatmap, works great

As the others said, get the light closer. Also, don't spray water so often, actually don't spray at all, just water the pot and let it dry well before doing it again. Since the pot is a little big for a seedling just water around the seedling, not the whole pot or you'll seriously over water the plant

The seedling is stretching for light. Try lowering your light to eliminate stretch. I have some seedlings that look like yours. If youre worried about the stretch then lower the light. Other than that I agree with Jeff, everything looks fine.

Looks fine
