Thanks. As long as it stays confined to the brugs, it's not a major reason for concern, just disappointing. I'm more concerned with providing a host plant that encourages a pest that can wreak damage on other plants I'm growing successfully. I took a magnifying glass and I can't see anything at all. I've only given them fertilize one time and the puckering was already there when I did that, so I can probably rule out feeding. For the minute, I'm not really doing much at all. As long as the plants maintain good color and continue to grow, I'll just keep an eye on them. If those leaves start turning yellow or getting brown edges or growth noticeably slows down, then I'll re-evaluate. Unfortunately for them, I'm not located in what would be a brug friendly climate.
