Hi there! So far so good! Keep up the great work and happy growing!

By all means, why would you want the plant to stretch? Specially with that amount of light? The key to success with los wattage is keeping the plant squat and the canopy even, since you will not have much light penetration. LST your plant as much as you can and don't let it stretch. Your final height should be 12 inches, meaning that in veg, the plant should not go over 6 inches.

it would be nice to add more light. more light

It looks like your light is too close. The leaves should be reaching up towards the light.
