Do I have powdery mildew or doing a good job?

That’s trichomes, dawg. You’re 100% good!

I hope everything came out good. What you were seeing is trichomes on the leaves.

Tes plantes sont magnifiques, aucune trace de l oïdium, elles sont bien givrées et plein de trichomes, mais aucun soucis. Bonne culture

Looks great to me, 1 or two photos had me guessing is it....? But i think your fine, think it was just those photos made it look iffy. I'm new to growing so may wanna wait for a more experienced grow for there two cents. I panicked initially on my first grow till i took a closer look and seen it was tric's. A loop or scope should help you determine that in the future. Helped me. GL hope you get a great harvest, looks like your well on your way.

Your grow looks wonderful! I think what you're fearing is powdery mildew is actually the trichomes and those are THE most precious part of the weed.... the more there are, the more they can look very much like WPM! Good luck!
