A.1 My tap water belive it or not is around 6.8
A.2 I always check tap water then add nutes then check again.
A.3 With the nutes added it goes down below my ph tester limit, so below 6.

The kit i got only had Ph down, so i am assuming that you can get Ph up???
Thank you for your kind words, my last grow in soil was a total mess up, 10 seeds 2 not come through, 2 where weak looking and ended up with 6 males, these are seeds from rhino seed called ice, i always say that you pay for what you get, my first seeds cost me £20 for 10 these ice seeds cost me £40 for ten and they 100% feminised (( aparently )). i will keep you updated if you want.
