Hey Steve, Yes mix your nutes first and in order. Grow, micro, bloom. Additives are just that don't count them in your tds. Mine could get as high as 2000 in full bloom with additives.. As for formula's, there are many. If it's your first folow the directions or look in the faq's section on GH 3 part and stage of growth. I use the lucas formula and see no difference with or with out the add ons. Some may be good I have not tried them all.

Let us know what you used and how it goes. It helps others that ask the same questions.. What strain are you growing ? Different strains do better with more or less. Someone may help you that has the same or has grown the same. Good luck. Peace.
LOC NAR on probation Reviewed by LOC NAR on probation on . addatives when you add things like humic and fulvic acid, sensizym, b52, silicone, voodoo juice and pirannah. the last 2 are root enchancers. does this increase your ppm and if so should they be taken in to account or first get your nutes to say 1000ppm then add all these additives which will increase your tds but not actually of increased your nuterient strenth. if i followed the advanced nutrient programme my tds meter would show higher ppm than wat the nutrient programme actually says it will be. one Rating: 5
