Rusty leaves

I’m starting to have rust colored spots on my leaves. Is this a problem? If so what can I do? Thanks!

Is this root rot? I’m using hydroguard and recharge

Leaves look like a nutrient imbalance so definitely open a ticket with support@grobo.io
The roots though I’m not experienced enough to say but does not look like root rot

My roots get that color also - I use Hydrogaurd, and Recharge. My plant is growing like crazy, and leaves look perfect. I think this is from the recharge, as it makes my water nearly black

Best way to tell is to feel the roots. If slimy and the res smells weird, then yes. If not then it’s just nute and recharge stain. Nothing to worry about. If it is slimy then your res water is too warm :+1::v:

That’s magnesium deficiency :+1::v:Add cal/mag in small doses until corrected

I just ordered some, how much should I use. And should I add it during next drain/fill or am I good just adding it anytime? Thanks

Summary

This ticket was made for Our Blueberry Grow when I didn’t clean the sensor one day:

The Nutrients should be locked in after knowing how well the plant takes to them: We use the same water every time:

What if we did this?: :question:

I meant to ask you guys, do I need to remove the leaves with rust colored marks on them or just treat with cal/mag?

Hey @Rx-78-2,

Those leaves won’t heal themselves, so once they are more than 50% crisp/spotted, they are not helping with the plant at all and can be removed. Focus on the new growth to ensure your Cal/Mag is being absorbed by the plant.

Cheers,
Stephen

I’ve removed the rusty leaves with more than 50% spots on them and added cal/mag after drain/fill. How often should I add cal/mag?

Until you see no more rusting. I’d also add it to my reg feeding schedule at half strength to prevent the issue from happening again :+1::v:
