There's really no such thing as a wash sale "violation". If a sale counts as a wash sale, under some circumstances some or all of the loss cannot be claimed with the sale and instead adds to the basis of the stock.
It's important to keep in mind that the wash sale rule does not care what account you trade in or what lot designations you use. You can even have a wash sale if you sell some stock and your spouse bought a call option on the same stock two weeks prior, even if you file separately.
The criteria for a wash sale are very simple. There must be a sale at a loss. There must be a purchase of a substantially equivalent security within the 61-day window centered on the sale. Those criteria are met here. So the sale of lot 3 is a wash sale.
Again, it is very important to keep in mind that your lot designations have no effect on the wash sale rule. It doesn't matter what accounts you trade in. The wash sale rule does not hinge on any of these things.
The more complex question is what effect the wash sale rule has on this transaction. In the worst case, the loss would not be deductible and instead the basis in the remaining stock would increase, raising your basis in lot 1 to $1,350. I believe that does in fact happen in this case, but I am not certain. Your broker (assuming this all happens in one account) will know and will work it out for you. But, unfortunately, if this is in different accounts, your tax professional will earn their fee.
