Yes....some ph up and flush the plant until the runoff equals the ph of the water you are pouring in the top. Usually it's 3-5 times the amount of the pot .....if you have a 1 gallon pot you usually use 3 gallons of water. (as an example)

I'm not a soil grower so can't help you there much but I know there is a good explanation of flushing in the Revised Sick Plants link. Check your ph runoff before doing anything else though.
