Stuck Fermentation Big IIPA, I think?

[Soeze]

I recently brewed a IIPA:

SG = 1.099
FG reading 1.071

Grain bill
29 lbs of Pale malt 2 row
6 lbs of Vienna Malt
1 lbs of Honey malt
3 lbs of DME
1 Cara-pils
5 lbs of honey
Yeast Nutrient
PH 5.2 Stabilizer

Yeast California ALE WLP001
Step starter from 2000 liters to 5000 Liters, two weeks of building, but I left it in the refrigerator for 4 mores weeks without feeding them.

I pitched at 68, then put in Ferm chamber at temperature range of 64/65 degrees for 2 weeks. I took a reading last night and it was 1.071, then took a brix reading and it said 1.090 (which can't be true), because fermentation took place over 3 days and evidences is in blow off hose.

I tasted a sample last night, which was good, but very sweet. Last night, I re-pitched 2 packets Chico and moved the carboy out of the Ferm chamber to see if that would get things moving, however, I saw no activity this morning (which could be premature to hope it would work).

Do you think it needs more time to Ferment and will the 2 packets of chico do anything? Should I raise the temperate to get the yeast to start again? What can I do at this point?

Something is seriously wrong here. You say there's definitely evidence of fermentation, and then it stopped, so I'm suspicious of how much fermentable sugar was actually in the wort to begin with.

You milled the grain, right? What temperature did you mash at and for how long? Have you tested your thermometer to verify its accuracy?

Yes, I milled my own grains
Mash Temperature was 150 for 60 minutes
The temperature thermometer is correct for sure.

Now you got my thinking about the milling of the grain. I was using the Captain Crush to mill my grains and had a lot of issues with milling with it. Troubles as will get stuck, or just free spinning.
