WOW! You added at least 20x the amount of gypsum for what would be considered really pushing the limits. This much Ca2+ in solution likely drove you mash pH into the low 4's. Not likely to turn out very well.
Read a bit on water chemistry and buy a gram scale. 25g of gypsum (1/20th lb) is about as much as you would ever add to a 5 gallon batch.
Yeah it was my bad.
Just out of curiosity, when you say not likely to turn out very well... bad taste? bad fermentation? what should I be expecting?
