......and epsom salt is not a ph corrector at all and neither is dolomite lime. The lime is used as a ph buffer, it keeps the soil ph from rising above 7.0 that is all it does as far as ph goes. You are a little on the late side for adding dolomite lime because it is not fast acting, however you can pick up a ph kit at any garden or hydro center. The kits have testing supplies and a small bottle of both ph up and ph down, this only costs about 20-25 bucks. Your plant is loaded with nutrients and water.
Did you happen to mention what soil you are using? Is it moisture control stuff?
Good luck
