Hi Luckkyseven! I have a suggestion on what to do: nothing! It's too soon in the season to see a growth spurt on
peppers. You should be hoping that energy is being channeled to establishing a good root system.
But here's also a suggestion. Take photos once a week of your garden, and close-ups of things in a spacial context (like, two plants together in a photo, or against a backdrop). This will accomplish two things.
First, when you compare this week's to last week's pics, you will probably see undeniable growth! (Like watching your kid grow, unless she's going through a spurt, you just don't notice that she's getting taller, but what does Grandma say?)
Second, photos are one of THE best garden records, especially if you have digital photos in a program that you can add comments to. So next year, when you are thinking that the
peppers are
growing properly, you can go back & see they look teh same as last year, and last year they wound up being 4' tall!
Good luck!
