and also dude, if you want to help speed the growth, i would go ahead and go to bigger pots before they outgrow those small ones and then all the roots are tangled up in a big mess. i put all my seedling directly into 3 gallon pots, with more area for roots to grow equals more upper plant growth and faster. also your lights are 26 watt? i think they emit around 1200 lumens each. you want to go for atleast 3,000 per sq ft sometime really soon. more light also means faster growth, now that they are young those lights are enough but always stay a step ahead of these kind of problems before they catch you. And its hard to tell from the pics, but from the color of the light it seems to be leaning more towards 2700K spectrum which is redish and good for flowering. For veg you want closer to 8000K which emits more of the blue spectrum plants love for strong stems, big leaves, and over all better/faster growth. And one last thing, i couldnt help but to notice your soil. It look to have alot of wood shavings as if you have soil from the front yard mixed with mulch. What those chips of wood will do is make little barriers in the soil that stop the roots and force them to grow around. This slows the root growth which in result does the same thing for the whole plant. So that may be a possible solution as to why you say they are growing kinda slow. but since they are already in there just leave them and transplant into a organic mix of soil and perlite. Its just soft enough so roots can grow easily and your roots will get more oxygen this way as well.
Good Luck, and keep us updated.
im glad i caught it before it was to late.
