I use both as well. I don't pH anything either. I collect spring water from a natural spring a few miles from my house, it's loaded with natural calcium. The water I'm using has been a game changer since I quit using tap water. Better seed germination and I've had well rooted clones as fast as 5 days using it. Best part about it, it's free. I smoke a joint while I fill up my jugs, throw em in the truck and I'm home in a few minutes. Well worth standing in the cold for 15 minutes each week. Megacrop seems to be just as good as Remo. My sativa dominant strains are getting 100% strength megacrop and my indica dominant are getting 50% strength Remo (separate autopot reserviors). Last week I tied a blumat into each reservior and I have my own bluelemon x bagseed cross females being fed by them. The two plants both look equally well pretty much exactly the same so far.
