Here are 5 CBD Crew Nordle seedling at 15 days from seed. Everything seemed right until they suddenly stoped growing. You can see on the second picture that the new leaves struggles to come out.. Here is the setup:
+ T5 lamp 50watt (30 inches from plant)
+ No nuts
+ Basic poting mix
+ Temps around 80 degrees

Any idea what is going on ?

50 watts T5 @ 30 inches in my opinion is not enough lighting, try lowering the light and adjust accordingly.

i started groowing with fluros, there great for plant growing, not only can you have them up real close to the plant, you can hang the inbetween the plantds to give the lower leafes some light

these are 5 days from sprout, one is struggling a bit but she's doing fine now (this pic is from a few days ago), just posting it so you can see how high the t5s are from them. IMG_20210420_111101627_HDR.jpg

4-5 inches is fine and once they are bigger you can get a little closer than that. If you only have one bulb then line the seedlings up in a row directly underneath it. Good luck!

I watched a video on YouTube recently and the guy showed what PH problems do to seedlings. Stunted growth is a sign of your PH is off. ‍♂

Your sorted now, t5 are high output tubes but run real cool, I kept my mother n babies under pll which are t5 bent over, keep close as you can with them, use your arm as heat test ! Great veg light for what they are ! What you using for flower?
