I have a 30 x 60 greenhouse. I purchased a tray of echinacea plugs from a reputable company, and they were beautiful. I potted them each into 4 " pots of sterile potting mix. I also added just a very small sprinkle of timed release fertilizer.. They sseemed fine for 2 weeks. I did fertilize my entire greenhouse with miracle grow liqua fertilizer with an injector a week ago. It is very warm in the ghse when the sun is shining. Today I notice that the leaves on the plants are turning brown and crisping. The centers of the plants look fine. Too wet? too dry? Too hot? to much Fertilizer? Or too much salt in my well water? Nothing else in the ghse is affected like they are..
