I've used the Flora series grow / micro / bloom. Nothing but success in two grows. One was water-farm drip/dwc and the second and current grow is ebb & flow. I use the General Hydroponics nute calculator. Half wy through my first grow I found that my TDS ppm was way over 2000 by following the nute calculator. I then used the same nutes but at a 50% decrease in my measuring and everything has been fine since. I've read other comments that the nute calculator (there are two or three on their web site) is a bit heavy on dosing. Has anyone else heard that?
Their calculator is designed for more robust flowering vegetables as opposed to our form of flowering vegetative state inducing substances. I usually go about 1/2 to 3/4ths their recommendation, but as always the plant will tell you what it needs.
