How much are you feeding you use a meter of any kind to measure also what type of water? Looks similar to issie i had in flower a week ago or so on a few leaves I fed a higher bloom and fixed it but could be ph lockout as well causing deficiency or sumn , you said weeks is it getting worse consistely and have you upped your feed lately

Yah, I ph the water to 6.2 every watering, have only fed limited nutes because it’s an autoflower, but it’s had rusty spots on the tips since it hit flower, everything else is fine, cal/mag??

I think closer to 6.7 6.8 better for absorption on some nutes but I'm a rookie. So no guarantee I'm right lol and ya spots normally calcium depending if your feed has it or not I imagine
