Jdog - I don't have equipment to test PH. Is it worth it to buy it now? I flushed each 2.2 gallon pot with 6 gallons of water yesterday so the PH should be somewhat normal... What do you think? I was thinking use flower nutes once a week (I have Canna Terra Flores) and then in one or two weeks flush again and just use water for the last two weeks (putting flowering time at 8-9 weeks). Sound like a plan?
