Hi all,

About a month ago I received 25 bare root strawberries in the mail and I decided to plant them in cups and start them in my windowsill (they get a couple of hours of light, but not what I would call an optimal amount). They had all been growing well up until a week or two ago ago, when I noticed that the edges of the leaves on most of my plants had been turning brown. Once the "browning" starts, it spreads throughout the whole leaf until the leaf becomes dead and dry. The strange thing is, however, all of my plants, even with the ones with the browning, are still producing new growth and leaves.

If anybody could give me any insight into what the problem might be, please let me know! I've attached some pictures that may be helpful.
