Root rot?

WeGrowstarted grow question 4y ago

I discovered some brown spots on leaves....please tell me that this not root rot 😨 Some leaves that looked worse had been removed last week, I thought that this was just a nutrition issue.

It would only be root rot if your overwatering heavily and the medium has got compacted to much causing lack of oxygen to the roots. I would also expect this to show on the whole plat not a new leaves. leaning more nutrition relayed. Check to confirm your feed is complete and providing enough for the plants. Good Luck!

I've got the same issue and I think it's damage caused by fungus gnats. They got out of control with my latest grow and my work schedule.. it's left a few brown spots on some of my leaves. I've eliminated so many other possible causes. It's either from the fungus gnats I had or its possibly a calcium deficiency but I don't think it's calcium.

Dark green leaves in meringue Is my girl telling me that the flowering fertilizer is too nitrogen loaded? I´m using top bloom from top crop, feeding at 1.4-1.6 Ec, and since last week I started to follow the feed-water-water schedule. The NPK of this fertilizer is 4-8-8. Should I adjust the input EC?

Brown spots and yellowing pictured above. My best guess is a Cal/Mag deficiency. Was feeding Botanicare Cal-Mag Plus at 1 ml/l up until ~2 weeks ago (friend has been watering while I was out of town). Before I feed her, any advice on what the problem is and how to correct it?

Brown little spots on leaves Hi, I went on vacation for 4 days, the ec went from 1.2 to 0.5 and many small dots appeared on a lot of leaves. Do you think it's due to that ? The ph went from 6.2 to 6.4 but I don't think that's it... Thank you for your answer :D Peace
