Summary:
Beginner level very very basic soil grow
4 plants
3rd week since germ
Accidental over water day 10
Ph on run off tested at 4 (very low ph) day 17
Tap water (ph 8+) boiled/sits to toom temp over 24+ hrs
No nutrients, ferts other than soil
Leaves on 3 plants are curled up on edges and some are "folding" in half and/or twisting under

Temp: 73-78 day
68-75 night
Hum: na, water kept in room for added air moisture
Light distance/schedule: 2 to 3" from top/ 16on/8off

Light doesn't seem to be of any issue at this time.
What concerns me are the leave characteristics.

I've read and studied a fair bit and am constantly learning more over the past 4 years. With what little knowledge I have ammassed, I do know that there are ways to help augment the nutrient supply in the event of nute lockup (folliar feeding etc) however I am still learning of these methods....

They will need more effective ventilation soon, and the soil ph will need fixing with some hydrated lime asap. However what else is there to do to try to help these wonder gifts of nature. Unfortunatley there is a budgett so if there are any home remedies anyone has!
