Baby lemons on Eureka Lemon tree
Why are some of the baby lemons turning dark purple? Also, some of the blossoms look like they are dry and are turning brown. Should I remove the dark babies?

Yes, and this is likely due to a phosphorus deficiency. I would fertilize each spring with a citrus fertilizer, dolomitic lime, and iron sulfate. This will give you tree everything it needs to bear fruit correctly.
