Hello,

I have three blueberry plants and a few sunflowers growing. They are all growing in pots, but the sunflowers are kept outside, and the blueberries are now indoors after being left outside for a while.

The sunflowers have started to have a grey-black powder at the edge of their leaves. Not all, but I broke them off and am hoping it won't come back.

Two of the blueberries started having reddish-brown leaves, which don't seem to have worsened since I took them inside. However, the plant which did not develop these leaves has just developed two small bright red leaves.

Please excuse the photo quality!

Here is the blueberry with the bright red leaf:




These are the browny-red marked leaves:







As for the grey-black powdery substance on the edge of the sunflower leaves, I threw the leaves in the bin. One has it very slightly, but not enough for it to show up on this camera.

Thank you.
