I use General Hydroponics 3 part Micro/grow/bloom/ + Floralicious and I use it all right up until the end cutting back on grow just a bit at the end I go from 5/5/5/1 in veg.....to 5/5/10/1+ kool bloom in flower then around week 7 in flower I'm backing down to 4/4/10 +KB - 4/4/5 = 0/0/0 ml/gallon
Hey thanks for the compliment but I've really only grown a few Auto's...It's just those last 2 were so nice it makes it seems like they've all been winners......not......lol.......When you get the good gene's they can make a guy look good.....That line recommends going all the way through week 7 of Flower with grow, micro, and bloom at 4 mL/L. So for an auto, keep feeding until about a week before harvest. It's a pretty basic line of nutes. Similar to the GH 3 part. I would do that and start feeding bud candy once you see pistils forming and big bud two weeks after that until about a week out from harvest.
@PipeCarver grows some impressive autos on here, it's worth checking out some of his threads.
