Hi-- complete gardening newbie here. We acquired a little garden plot last week and decided to try our hand at some vegetables. Got some kale from our local garden center (one variety was White Russian; not sure what the other was) and planted them (again about 1 week ago). They looked healthy initially, but are now deteriorating rapidly. Three photos posted above; in the first, some of leaves are showing some early white spots; other are more white, and those areas essentially feel dry, crumbly, and dead. The second is a different plant in a more advanced state, with some leaves with holes. The third is a plant that looks healthier, but have these beetle-like insects on them.
We have planted other vegetables (spinach, chard), they do not show any of these signs.
Hoping someone can provide a diagnosis; are these doomed and should we give up on them; what can we do differently next time; are the insects related or otherwise harmful?
Thanks for any pointers.
