My Gerbera flowers have been blooming well but one of them one day came out a bit distorted, looked like it never fully bloomed, the rest were happy and healthy, but now it’s happening to a few others and I am concerned as I cannot find an explanation for the flowers being under developed and still a bit green. The initial plant I have noticed looked like it’s a bit stained under some Leaves but not all, The second plant is normal in the leaves colour but two new leaf shoots are staying a bit curled as in the image. The third plant is also a bit stained like bore water underneath some of the leaves but not all of them I cannot find any image online to match my Flowers and they’re looking pretty sad ??
