They look good. What nutrients? what's your water ph? Small amounts of the right nutes are ok but it's really hard to tell without info on the variables.
When mine are in the late seedling or clone stage I use a homemade organic tea with a few supplements at about 800ppm ph to 6.3 and a week later I up it to 1200ppm but I grow in coco/soil and I use Veganic nutes. Not saying it's the right way just an example.
