First grow rusty leaves

[Matto]

Hi Members,
Can anyone enlighten me on what deficiencies I may have here please?

Much appreciated

Hey man. You gonna have to fill out the infermary sheet. Answer some questions about your grow setup etc.

Hi thanks but I think I have diagnosed through the guides

Rust can be caused by too much fertilizer, or by a need for CalMag.
Better help might be available if you specified grow style, pH, ppm, etc.

Following deficiency charts can cause you much trouble, because most deficiencies are caused by something else, like the things above.
Fixing the symptoms probably won't fix the underlying cause.

@Shrederr DWC i use general hydroponics a little under the recommended. I use cal+mag as directed on the bottle. Have been away for a week and ph was down at 5.3 when I got home.

- P lockout for sure, but it's a bit odd to see it hit so strongly on the top leaves only? A micronute defc. could also be in play, or both! What's the T and RH% in there? ..thinking bad VPD may be making this worse....

I think this happened to me when I used big bud and overdrive together.
