Yea Lucas is general hydroponics 7ml micro 14ml bloom per gallon.(or just 1 tsp per gallon of maxibloom powder per gal) I like the powder because it has a bit better ph buffering to it. You run that ratio through the whole grow. Make it weaker for seedlings. Has just enough N to work in veg and good pk for bloom. I ran this for years...and tried it side by side with a few things....the Lucas always came out as good or better...and always cheaper and way simpler. Megacrop I like because of the powder, it’s ph works good with my well water, and it’s slightly cheaper. I occasionally try something new just to make sure I’m not missing out and to mix things up, but I usually switch back. Environment is a way bigger factor imo. People worry way too much about nutrients...but they would be way better served dialing in their grow area.
