you can get a CFL or two to use for your clones. they don't need much light and it doesn't need to be as close as it does for a vegging/flowering plant. probably just needs to be within 8-12". (the plant is not so much worried about photosynthesizing as it is root production.)

if it's just the tips of your clones than this is normal. your plant is using up nutes in leaves as their are not roots.

soil or hydro?

if you have a therm/hyg. then put it inside your dome. get a temp and humidity
