there's a couple of reasons your seedling isnt growing as fast as you would like. Number one, temperature below 23°C (73°F) will slow down growth a lot. Number two, Since you are using a pot so big for the stage of development it is now, you are over watering; for example, 200 cc of water should last the seedling 4 to 5 days easily and you are giving them more than that daily and so the roots are literally drowning and can't uptake oxygen. Both reasons combined will keep the growth rate to a snail pace.

hi you have found the solution, leaves are curling up, most time because of heat, we say they are cupping or tacoing. Keep the roots of the plants humid and cold ( maybe digging your container into the ground or putting your container into a much bigger one filled with soil) paint the container white, put the plant in the shadow, put wet clay pepples onto the layer. just look how the roots gt a cooler envoirement. Roots dont like heat, they start dying if its to hot for them
