You are right on the edge, but I wouldn't be overly concerned,
especially since you aren't adding CO2. The KH and dH values
of my raw water are very similar to yours. In tanks with fast
plant growth I add calcium chloride, magnesium sulphate, and
sometimes baking soda. From your description your tank would
appear to be moderately stocked with average plant growth. Just
do your weekly 1/3 water changes keeping an eye on the pH.
