Yeah, thats it. When I say tablespoon its actualy a tablespoon plus 1 ml. Because a tbsp is only 15ml and L's formula calls for 16ml. Another way to look at it is to say it's 1/3 cup of Micro and 2/3 cups of Bloom per 10 gallons.
I think the confusing shit you saw was the addback chart. If you change your res every two weeks you don't need to addback anything but water. The reason they have the addback chart is because people run this shit from day 1 to harvest and never change the res, they just keep adding back nutes.
Yeah, I suppose that Micro is a bit of pain getting the shit all over the tables...
IMHO Organics in hydro will cause more probs (clogging pumps, stinky resevoirs) and not give you any better taste or yield. Me and my buddy just grew the same exact shit in soil, we both started out all organic, but in the 3rd week I went to L's Formula, and he stuck with bat shit and fish shit, etc... he flushed, I didn't, neither one of us could tell the difference in taste. We haven't cured them yet tho, this was just a sample, in a couple weeks we will know for sure after the curing. Feom what I have seen so far, no difference.
