They've been growing alot this week, their also getting smellier by the day. With the lower ec feeds they seem to liking also, will probably continue unless they show some kind of issue.
Looking good! Sort of surprised with your PPM at 500. I'm using Jack's and a bit behind you and I was following the various Jacks feeding schedules so I am already up to 900 PPM. Wondering if I should back it down now...
