So here in the northeast zone 6b its been on the colder side of temps for this time of year. My 3 blueberry bushes all have alot of blooms/buds but the leaves are small and sparse: Is it to early for the leaves? I did a garden revamp last year , soil test and amending the soil .
I can take pictures tomorrow if needed.

They have had a tough last few seasons. Between deer and deteriorating soil conditions. Soil has been improved per soil testing . Plants where 2 years old when planted and are now 6 years old
Year 3 they did very well, this season has the most flowers I have ever seen.
Did a complete garden over haul last year with soil test and amending.

The PH is fine with blueberries but as you go to adding things it can get changed a bit.

Blueberries do not like nitrates as a source of nitrogen. It is toxic to them is what I've read. Look on the fertilizer and if it says nitrate/nitrates anywhere avoid that kind. Ammonium or urea is fine to use as a source of nitrogen.

It doesn't say if the results are in ppm or lbs/acre. It looks like ppm. Do you see where it states that anywhere?

So according to that you need about:

25 ppm N = 50 lb/acre N
30 ppm K = 60 lb/acre K
11 ppm S = 22 lb/acre S
0.3 ppm B = 0.6 lb/acre B

The fun part is trying to figure out what fertilizer to use without adding things you don't need.

Can't use potassium nitrate because it contains nitrate so that is out of the question.

If you use the Expert Gardner Azalea, Camellia, & Rhododendron Plant Food 10-8-8 from walmart (miracle gro has the same version),
and use 1.5 cups of it and spread it out in 80 ft2 area evenly. That will provide equivalent of:

50 lb/acre N (25 ppm)
40 lb/acre P (20 ppm) Going to raise phosphorus to high.
40 lb/acre K (20 ppm)
25 lb/acre Sulfur (12.5 ppm)
0 lb/acre Boron (0 ppm)

I used espoma version of above , I will be doing another soil test end of season anf see who things look. Like I said last 2 season they where much worse so Im atleast happy to see new cane growth and lots of buds. So hopefully they are on the mend.

How much did you put down on that 80 square feet?
Dont know if I did this right but I used about 3lbs per plant lightly worked in around the “drip line” very early spring.
Like 1st day of spring
I figured each area around my bushes are 9-10 sqft
Theres not much in those bags percent wise.
Im still unsure if I understand the soil sample instructions and fert application rates. My calculations came up much higher than the 3lbs I applied ?
Any how we will see. Garden got so out of whack I dont expect rapid change.
Seems for the past 5 years I have not been adding enough amendments and or the compost I have been getting is not very good either. Soul test before the ground freezes this season and work at again next year

Test says 2.5lbs/100sqft
.025lb/1sqft

9sqft of plant space x .025= .225lbs

4lb bag 4-3-4 = .16lbs nitrogen .04lb per 1lb
.225 lbs needed /.04 = 5lbs per 10 sqft
I applied 3lbs was not sure I did this right.

When I do it this way
.04% / 2.5lbs N needed its 62lbs / 100sqft?

Had a brain freeze for a moment.
I did not put down 3lbs per plant. I was on auto pilot I guess
I put down THREE CUPs …. Because nothing was making sense to me
