Default getting discouraged!!! please help!!!

so the past few batches i've made have all turned out under on the OG.for the most part not way under but under.i've made most of these multiple time and i know what i should be getting for an OG.but last night really discouraged me.i made this recipie and ended up with a measly .032.i'm really starting to get frustrated and don't know what the problem is.the differences from the recipie below are my mash temp was prob 159-160 and my sparge water i brought up to about 185 which i typically do so i really don't think that is the problem.any suggestion on what i'm doing wrong would be greatly apreciated!!!!!!!

Do you crush your own grain or buy it crushed? My first few AG batches had very low efficiencies (50-60%), untill I bought my own mill. Now I consistantly get 75-80%.

My bet is that it is the crush.

I can't seeing that low of an OG being the crush unless the grain wasn't crushed at all.

Using Beersmith it shows you have 43% eff. That is really low, I mean based on that to hit the OG estimated you need 9# of each of the base malts, which at that level will lower your eff even more. Something is really off. Either the crush of the grains, your MLT, the sparge temp, volumes, or water PH.

Do you have any tools to try to double and triple check any of these? Mutliple thermometers, graduated cylinder, a grain mill, PH meter. I would see about getting those and finding out where the problem is.

Also do you stir your mash after dough in?

Your Mash time of 45 minutes seems a little short. You may want to increase that to 60 at least. Also when you sparge how long do you let it rest. I always rest 30 minutes after adding the sparge water?

Is this your first wheat beer? I always have issues with wheat.
I even did three, one gallon test batches with wheat where I used my coffee grinder to make the grain look like flour. I still had low numbers.....

you may want to check the accuracy of your hydrometer if it suddenly showed up without any changes.

ok i'm gonna try yo ansewr everyone's questions
1)i had my lhbs crush the grains for me and they seemed to look good.
2)i double check my thermometers every time b4 i brew(learned that the hard way)i do not have a ph meter.it's never been a problem in the past but that is definitly the next thing i'm gonna check
3)i always mash for 60 min.i've just never changed it in my beersmith.when i sparge i just add my water and stir for a few minutes.i thought it was bad to let it sit in the hotter water?
4)already double checked the hydrometer too.
