over-watering?

heres the shpeel....every since my shit sprouted the leaves have been seriously curled down. new growth will be goood then slowly curl. My first set of true leaves slowly yellowed got brown spots then croaked.

got three plants just over 4 weeks old and one clone.

soil is organic and contains peat moss, lime, perlite, and composted materials. I also added another 20-25% perlite.

humidity between 40%-70% at the most ... usually 45-60

temps 69 at night- 75 at the most. sunleaves pioneer cfl tubes spectrum for veg used to be 10-15 inches away at first...moved within 5 inches last week with the appearance of more leaves.

I don't have a ph tester yet (i knw don't give me shit its on its way) i use distilled water. a week and a half ago i ferted one with 1/4 strenght earth juice grow which killed that first set of leaves that looked like shit promptly and grew a bunch of nice new leaves...which curled under within the week

i have a clone too with some serious curling action.

i think i may be overwatering...i do it every 3ish days and i do it very thoroughly. soil does seem a little to wet when i squeeze it. maybe i need diff. soil. if this is the problem then how could i remedy it? transplant? They are just in tiny cups with holes right now so they're ready anyway.
otherwise i'm sure its ph which i can fix next week when i get my tester.
Thanks for reading.

yu can easily transplant those, but be careful! to not broke roots, if cups are not class the its easy to cut the sides very careful.
and yu have been overwatered them.. so wait that soil is dry out 2-4inch and then little bit water, but it depends on plant size so pics are welcome and needet here !
and when transplanting the plants, get dry or fresh soil and cover the sides accured and then watering the soil for good... little water not help and too much is massacre so just nice watering !

At 4 weeks the plants will do better if the soil goes through wet and dry phases it gets the most nutrition from the soil this way and yes you are overwatering
