@kaneownz, yes its my first grow. I startet now with tomatos a Micromanagment. Ty i try my best good luck to you (Sry for my bad englisch im from germany)

@JustmeJ, Hey, I know the time has passed, but my guess is the early brown spots were from drops of water being on the leaves. At certain angles and intensities the light can create a magnifying glass effect with the water droplets and make burn marks. :)

until now I had a glass bulb over the plants. now i covered it for one day. with some wind and about 25 ° C why do you have white spots now?

@raptor65, thanks🤩
