Very odd. I've run Mega three times now in auto pots and have never had this problem. I mix mine in a shaker, AND mix it again in the bucket with a paint mixer in my drill. Did you clean the res between grows? If so, did it get a good rinse? I would suspect it reacted with something that had been in the res previously. I can think of no other explanation. I'm on Greenleaf's thread on RUI and have not seen anything like this there.
Hey folks, got a question/problem.
I'm not a participant in this autopot test, but have been following the thread closely since I've been using autopots now for continuous grow cycles since May 2017. In May 2018 I jumped on the GreenLeaf MegaCrop (and its companions Sweet Candy & Bud Explosion) bandwagon -- but initially in AirPots. Had great success, independently, with autopots and with MegaCrop.
Now the problem. This past September I ran a cycle combining MegaCrop and AirPots. What a disaster. The brew separated in the reservoir and clogged my lines. Not just once or twice, but at least a half-dozen times. I had a small pump in the reservoir. It didn't help. Eventually it clogged, got cleaned, clogged again, and finally died. Have a look:

Here's the head-scratcher. I had exactly the same mix/brew in a 5-gallon white pail that I used to hand feed fiber-pot plants over in a different tent. That mix DID NOT separate. So what's going on.... exact same mix in a black plastic reservoir and a white plastic pail. One separates, one doesn't. Is GreenLeaf racially biased? I doubt it. There's got to be some rational explanation. But unless I can get to the bottom of this, I won't be using MegaCrop with AutoPots again.
