No, a landlord can only deduct for extraordinary repairs, not ordinary wear and tear. Also, you have a right to an inspection BEFORE you move out, so the landlord can identify problems and give you the right to fix them.
Given the dollar amount, you could (and, in fact, your only resources is there) bring a small claims action.

Landlords have to live with normal wears and tears of the rental unit. Security deposit is tenant's money. The law permits security deposit to be made part of the lease to protect landlords against excessive wears and tears.
1. $350 to reseed and repair the lawn. This may or may not be chargeable to the tenants. If the reason for it has to do with the neglect of the gardener. Then this charge is not permitted. It's a question of whether you damaged it. You should look it the lease to see if it is your responsibility to maintain the lawn. If it is, then there may an issue.
2. $1,000 to rebuff the and finish the hardwood floor. It they are not deep scratches, I would say the finishing should not be chargeable against the security deposit.
3. $500 bleach scrub/acid wash of kitchen laminate floor and bathroom grout. I would say that's normal wear and tear.
It sounds like they can all be challenged.
