It doesn't look to bad, just needs some tweaking.Not enough soil in the pot, not enough Perlite in the potting mix, very poor reflectivity, no centralized lumantic location, lights tooooooo! ..high(1-2 inches please) light wrong color, (one each of 2700k and 6500k or all at 4000-ishk is good)
no fan...limited knowledge on plants breathing abilities, google stomata, no fire insurance ...check with Mom.. scale 3/10 for effort
