That's a bitch to test the ph using the drops, there is no definitve answer without a PH pen. I do know the Nova Series has PH buffers so you don't have to adjust it as much. I got a cheap PH pen when I started for like $30 on E-Bay, it was slow but accurate.
I did use Liquid KoolBloom through the entire flower, and powder KoolBloom during the second half of flower. Like Stealth Panda said, get alot of 'K', I'd recommend A.N. Hammerhead, Botanicare Hydroplex or Humbolt's new Deuce-Deuce(0-0-22)
Sup everyone, I am curious if any one has used Humbolts Deuce-Deuce 0-0-22 before? I was going to use Hydroplex Bloom or Technaflora Soluble Seaweed Extract, but Deuce-Deuce is looking good.......:eyesmoke:
it takes a little while to get the circulating kit from GH to start running water consistantly, it spits it out for a while then runs smooth. I know mine was working great when the controller had a lot of hydroton sediment in there the next day(usually found in the buckets)
my first one I chopped at 61 days, my last ones I let go for 68 days. The extra week is very noticable as far as the high, waaaay more potent. The shit just plain fucks me up, for a while too.
