I don’t seed to good how far is you light? , what stain? Auto or photo? And what is you pH ? Maybe @Budz , @2GreenThumbs , @Covertgrower they have more experience and more better look
If that’s in soil, you need to be around the 6.5 mark on PH. The spots look like you may have dripped some water/nute mix on them, happens to me all the time but isn’t an issue as long as you don’t see it spreading. I use Calmag until week 6 flower fyi and adjust as the plant shows me.

It does look like the start of a Cal-mag issue. But not 100% sure either die to the fact I don’t have problems.

Welcome , tips of the leafs showing very slight Nute Burn. I see one little rusty spot you might start you a half of a dose cal-mag next time you water.
Happy growing !
This is the Plant as a whole the bottom leaves looks healthy for the most part no yellowing nor any are dieing off
I seem to be having something similar happening with a White Widow Auto. 8.5 weeks from seed. Appears to have spots on the leaves that look like a brown rust color. I ruled out fungus, as it does not rub off. I also appear to have some curling of the leaves. I’ve been watering, using Botanicare nutrients, Cal-Mag, Grow and Bloom. Only Cal-Mag and Bloom in the last 3-4 weeks. I started adding some Molasses about 3 weeks ago, just once a week. Always adjusting to Ph 6.5-6.7 after adding nutrients. Everything was going slow but well, until about a week ago and noticed the spots. What gives, any help or direction is appreciated.
