first time grower of white widow outdoors

I have a couple of questions. First, I have 4 plants in soil growing in pots outside in the natural sunlight. They are about 5 weeks old and about 5 to 6 inches tall.

Is this a good size for 5 weeks outside?

yes this is a good size. mine are about the same size as yours

if your in summer no thats terrible. when my plants are outside in summer they would be about 1foot or taller after 5 weeks

do they look healthy ? how often are u watering and what size pots.

that all depends on the strain and location tho. so that doesnt mean its terrible
