that one that you thought were 2? its not, in the pic you can clearly see that something nibbled it off and it created 2 tops. i have no idea about the brown leaves, but the one with the white spots may be mites or just a burn from the leaves getting speckled with water or nutes.(or cow slobber lol) you obviously have a farm somewhere near for the cows to escape from, or you have elk. the other thing, is that a mulch around your plants or is the planting hole really that small? if it is the later, they are small because the grasses are stealing nutes and fighting for root space.
