Brown Edges on Leaf. Bit of yellow and purple.

Chow_13started grow question 5y ago

What could be causing this? And how do I fix it with GH flora series. It is only showing up on one bud site. But I believe its getting worse. I also noticed other leaves all of the jagged edges are slightly curled up

Looks like you have a potassium deficiency or lockout, this causes the edges of leaves to appear burned like the ones in your photos.

So how would I treat it. When this started I was doing a ratio of 1 Gro 2 Micro 3 Bloom. But after I noticed this I did a reservoir change and changed the ratio to 1Micro 2 Bloom. Not using grow at all.

Continuing calmag deficiency What I think is a calmag deficiency started about 10 days ago. At first I thought it was too low PH (6.0 - 6.1), so I corrected that, but no luck. Then I started adding biobizz calmag, still no luck. It seems that the deficiencies are picking up speed again. Any ideas appreciated
