I like AN pH Perfect nutes with RO water so no dickin' around with pH or running into problems caused by town water that comes in at 350ppm of all sorts of crap that will cause lockouts and toxic salts buildup.
What with GH, Botanicare and Gavita being owned by Scott's Miracle-Gro/Monasanto/Bayer I wouldn't use them to feed my stinging nettles much less my prized pot plants. Damned if I'm giving money to support companies that have denied pot users and actively put up roadblocks to us all these years.
Hearing lots of good things about MegaCrop so if saving a few extra dollars per grow is important then you might want to look into those. I won a bag in the contest they had but shipping to northern Alberta would have paid for a few extra gallons of AN 3-part so I passed on that. At $40/gal that will last 5 years or so I'm not worried about saving a few bux on nutes when my power cost 23.5¢/kwh so almost $90.mth to run a 1000W light for 12 hours/day. I only change nutes once or maybe twice each grow so save all my money by not tossing out perfectly good nutes every week or so. Rhino Skin and Big Bud are the only other two AN products I use regularly and bought GrowTek CalMag and keep some Epsom Salts handy. 17 years and haven't ever had a problem I could blame on the nutes.
I never have used beneficial bacteria and get massive root growth with my nutes staying clear and clean at the end tho I do use a chiller if needed to keep temps down or peroxide if not using the chiller and temps get over 69-70F.
Setting up a couple tubs today to get my DWC going again. Tired of playing in the dirt for half the yields.
