Blueberry fertilizer options

Guys, I recently had a ph test done on about 6 of my 20 plants and the ph ranged from a low of 3.8 to a high of 5.0. I have used ammonium sulf in the past but given the low ph numbers I am seeing I think it would best to try something else this spring. I was thinking about a general purpose fertilizer like miracle grow but wondered what others might think.

Don't use anything loaded up with nitrates. I've read that Urea is good and doesn't lower the pH like ammonium sulfate.

I remember one of your posts last year about Fish/Kelp/Molasses.That shouldn't do too much at all to the pH. Brady

I am using Schultz's Plant Food, acidic formula, mixed at one tablespoon per 4 gallons of water, 4 applications per shrub per year, in March, April, May, & June, on each of our blueberry shrubs. This is a minimal amount, enough to feed the flowers and stimulate woody growth. Our shrubs are healthy & productive, but I am not seeing commercial yield level.

Another option that is cheap and easy to apply is cottonseed meal. I got a 40 lb. bag at a feed and seed store for around 25 dollars. I threw a few hand fulls on my 2 year old plants and they really perked up. Besides being cheap, cottonseed meal organic, slow release, will not burn the plants.
