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
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.
