these are just babies they don't need much light. however I can see they are a bit stretched. With that light I'd sit at 30" @ 25%. as they enter veg you can increase gradually to 100% sitting at 24". You can gauge this by looking at your plants. if they look tall and stringy like this they want more light. if they're curling and burning it's too much light. For water just hit em' when they're dry. they dont need much at this stage, just feel it out. if you watered that solo cup through you'd probably be good for a week

my answer will be alittle longer, growing sucessful automatics work like this after germination give them the final pot, Imaa taking smartpots with at least 11l / 15 l filled with afluffy, good draining MJ soilmix, iam mixing my own but the biobizz lightmix/ allmix/ or plagron royalmixare very good MJ soils. they are light prefertilissed so you just have to water for weeks give the ne seedlings" open domes" ( halved plasticbottles with holes), until they show up properly loook for them twice aday, and spray / water under the domes ( 20-40 ml) start feeding if undder leaves look yellowish or the hole plant is pale normally around week 3/4.... or in trasition to flower stick with your veegetation nutrients now until they are ready with the sstretch, because now they neeed a good amount of nitrogen for the stretcch after that you can change to the flowering nutrients The lightdistancee in the beginning should be 70 cm abbove the surface of soiil the light remain in this distance, the plants grow towards the light
