That was useful thank youSetup looks good, and you have walls that are capable of reflecting a lot of the light that hits them. But have you considered switching the lenses in your COBs to get a tighter footprint, so that less light hits the walls (instead of the plants) in the first place? Or adding lenses, if yours are open? Might boost your yield a fair bit.
Either way, you should be happy on harvest day!
An EC meter won't accurately show how many parts per million of total dissolved solids are in that brew - it's "organic." I wouldn't expect there to be much in the way of dissolved nutrient salts or the like in it. They don't directly measure content; they just measure the electrical conductivity of the solution. If it's a "TDS" meter instead of an EC one, it just does the same thing and then multiplies the result by a simple conversion factor (typically .5 or .7, IIRC - which is just "in the ballpark range," anyway, since the various salts and other electrically-conductive elements/minerals in ("chemical") fertilizers have different degrees of conductivity... so they all read a little differently from each other).
