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.
Hmm okay u know what still not sure if its calcium or nute burn..... Under developed buds.. sign for nute lockout.. please, do tell more about your feeding habbits, buddy.
@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....
