Hi Weed..

you should do fine with those temperatures as long as you have GOOD airflow.. lots of fans blowing around the room..

Will your lights be on at NIGHT time.. or DAY time?

It is always safe to water with 6.8 PH water... If you know your soil is higher than 7.0 then you may want to water with 6.0-6.5

Or if you know that your soil is 6.0 or lower you may want to water with 7.0 water... You definitley don't want to make any careless decissions and over compensate.... LOL
