[understanding test strips readings]

Started my 37 gals around July 8, planted 1 Dwarf Sagittaria, 1 water sprite, 1 baby tears and 1 red melon sword. I cycled my water for about 3 weeks using prime, stability, Fluval hang back filter with sponge, carbon and bio wheels. last week I added an established filter sponge from local fish store along with 6 male guppies. I'm hoping to add more community fishes each week.  Now can someone help me understand my water reading, I'm using aquarium co-op test strips. What ranges do i want to be in for community tank along with future shrimps. 

Nitrate --- 10-25

Nitrite --- 0

Hardness --- Hard --- 150

Buffer KHPPM --- 0

PH --- Low --- 6.4

Ammonia PPM --- 0

is my water ok or should I be in full on panic?

any help is greatly appreciated.

Thank you
