Hello I’m new to the forum , I used to grow 12 years ago but was not the best. Now I’m trying again but this time really trying to put in a full effort here is my setup and issues . Any help would be greatly appreciated

3x3 tent
1000w mars hydro led
Light is 16” from cano
Coco coir with 30% perlite
Gia green 4-4-4 worked
Strain is bruce banner
2 plants roughly 3 weeks into veg
4 clones just about rooted
Temp is 23-26 degrees
Humidity is 55-70%
Fresh air duct was just added
Air exchange is always on low
Fan on moving air but not directly at plants

let me know if I can provide any other details to help with the diagnosis.

here are the pics of the two with issues
Thank you very much for the help
