New Session IPA - Attempt 1 Brew Session

Trying something new -- I'll be adding an extra 1/2 gallon that I plan to throw out to help with keeping hop debris out of the fermenter. Trying something else new -- adding a little Calcium Chloride CaCl2 and Gypsum CaSO4 as recommended using this tool (http://www.brewersfriend.com/water-chemistry/). Target water salt additions will be (for 11.02 gallons RO water): Baking Soda: .5 grams Gypsum CaSO4 = 11 grams Calcium Chloride CaCl2 = 4 grams Specific Amounts: Mash - Gypsum: 5.739564428 grams Mash - Baking Soda: 0.2608892922 Mash - Calcium Chloride: 2.087114338 Sparge - Gypsum: 5.260435572 grams Sparge - Baking Soda: 0.2391107078 Sparge - Calcium Chloride: 1.912885662 Note, these additions are for the total water volume of 9.26 gallons, so it should be distributed as needed equally to the mash and sparge volumes. Collected .25 less water than expected, which I think was due to evaporation heating up mash/strike water. I used my 20 gallon pot to heat liquid this time, and the large surface area has high evaporation. After primary fermentation, dropped temp to 60F for 1 day. Brought back to 70F and added dry hops on 5/3/2016.
