Bruce Banner DWC

So that’s not how you use GH flora trio.. if you just bought the gro bottle you need micro and bloom immediately. Maybe calimagic if you’re not using tap You’re missing much of the needed nutrition just running flora gro. Now here’s my suggestion - when you get all 3, I’d run 2 mil micro, 3 mil gro, 2 mil bloom per gallon. Shoot for 400 PPM or so. I’ve run DWC and flora trio for years. Not as much with autos so that is just a educated guess compared to what I would give for a photoperiod at that stage. Increase slowly, and then adjust when it starts flowering. GH has a feed schedule on their website- just cut it in half for autos to start. Good luck

100% she needs some nitrogen and maybe a little bit of other stuff .. I recommend hygrozyme for dwc. It's the king of kings for keeping roots in tip top shape
