i don't use a soil pH meter - I don't trust those cheap things and even if your soil was off, what are you going to do? you always want to feed pH'd water - so what else can you do, flush I guess but I think the important thing is the water, not the soil
watering everyday is not a good thing
soil needs to dry out between waterings, and each watering should be a good drenching. water till it starts to run out the bottom. depending on temps, size of plants, and humidity, I water every 2-4 days.
moisture meters are OK, but after a while you can just tell the moisture content by the weight of the pots
that's just my take on it. it seems to work for me.
