I'm starting to wonder if I should've added more sugar, or that 200g bag of primer. Either way I guess I'm shooting myself in the foot here wondering if this can be saved! Seems like the 3/4 cups may not have been enough?
Yep, Generally the coopers are "Kit & Kilo" kits - i.e. the 1.7kg of hopped malt extract and 1 kilo of sugar (either dextrose/corn suger or DME). The 3/4 cup is a general rule of thumb for those who bulk prime when they bottle condition - after the beer has finished fermenting they transfer the beer into a bottling bucket with 3/4 cup of corn sugar which has been boiled in about 1-2 cups of water.
Has it been fermenting long?
You could add more sugar now but it might be hard to get it to dissolve without stiring and introducing oxygen which you don't want to do once fermentation has started to slow down. You could also take the DFH120 approach and add a little bit every day or so (200-250g for 4-5 days).
or you could just let it ride and end up with a "session" IPA at about 2.4% ABV.
I think most would suggest getting away from the coopers kits reasonably quickly, but at the vary least look at adding DME instead of sugar will improve the kit a bit.
But the best bit of advice would be try using a yeast not from the kit - fermentis US05 is my normal choice for dry yeast, and try keep it at the temp it likes between 16-20°C
