So, I'm sure everyone knows about the Lucas formula. G-M-B (Grow-Micro-Bloom) 0-5-10 - For Vegetative cycle (24/0) 0-8-16 - For Flowering cycle (12/12) Now, I have purchased Grow, Micro, and Bloom. Is there any use for Grow at all? I'm pretty new to hydro growing, but to me it would make sense to use grow. I've been looking for different nutrient soup opinions, but it looks like the Lucas Formula has a monopoly on it! I'm wondering if anyone has any evidence that using Grow is bad or good. If it's bad, I guess it will have a nice place sitting in my basement doing nothing, heh.
