    Brown/Rust markings on leaves. Any ideas?

    That's doesn't seem to be of much use. If you could answer my question, that would be more appreciated. How many tablespoons of dolomite lime do you add per gallon of soil in your grows? This would be useful information going forward. I do not plan to implement it now, but for the future...

    Brown/Rust markings on leaves. Any ideas?

    Seems my pH is indeed low in my soil. Most likely the culprit in this situation. How much dolomite lime do you tend to add? Seems the consensus online is around 2 tablespoons per gallon of soil. I'm interested in how much you guys like to add. Thanks in advance!

    Brown/Rust markings on leaves. Any ideas?

    Thanks for the messages. All great advise and will certainly take it on board for next time. Particularly adding some dolomite lime into the soil. However, I still don't have much advise on how to resolve my current situation in day 28 of flowering. From the previous messages are you...

    Brown/Rust markings on leaves. Any ideas?

    Thanks for the reply. Could you please elaborate? I can test the soil pH tonight properly. Not just the run off. How do you suggest is the best way to measure and then alter the pH if required in soil? Thanks in advance

    Brown/Rust markings on leaves. Any ideas?

    The soil I'm using is Canna Seed Mix. It has a pH out of the bag of 5.7 My pH run off varies between 6.0-6.5 I'll do my best to keep it above 6.5 going forward. Hopefully this will correct the issue. I'll update in a couple weeks time. Thanks for the responses.

    Brown/Rust markings on leaves. Any ideas?

    Need some opinions on a leaf issue I have. Can't figure it out. Any ideas would be much appreciated. Quite distinct markings. This leaf is about half way up the plant. Newest leaves have signs of rusting too. Thought it could be potassium deficient, pH fluctuation, calcium/magnesium, light...

    Leaf deficiency. Not sure which one?

    Not considered pH fluctuation. Good point. My run off was on the low side was around 6 and wanted to raise it a bit. So have been watering with ph 7 to bump it up. So could well not have liked the sudden increase around the roots. I'm dosing my CalMag at 0.4EC. Watering with plenty of run off...
