Hi Zen Man,
I came across your name regarding zinnias and their issues on a few sites over a long period of time so it seems you are quite knowledgeable about them.
I joined here in order to seek out your expertise.
This is my second year growing zinnias for cut flowers. This year I used seeds from Botanical Interests.
Seedlings are about four inches high and I am noticing a few branching already which I thought was early since I haven't pinched them. And on those there are deformed leaves. The are pinching together and narrow to the end, almost what is would look like if a Caterpillar was making a nest, but no bugs.
I'm assuming a nutritional deficiency or something but I have very little experience and am not finding the problem online.
Any thoughts? Thanks in advance.
