Rust spots

[Reighreigh]

Can someone tell me what the problem is here?! Week three- autos. Starting to get brown-rusty spots.

How much Calmag supplement are you using? My personal experience indicates that a little extra, than Nebula Haze's guide recommends, prevented that.

Also, to help in the future, list what your setup is in your profile. It'll help the rest of us make recommendations. Good luck!

Yeah - what's your setup? Looks like its starving for nutrients - maybe nutrition lockout?

CAL-MAG!!! That’s it.
