Res size for 3x3 OD flood table

I use my flood table for flood and drain hydro with rockwool cubes. Last run went well with a 17 gal reservoir, changed once a week. Im thinking about jumping to a 27 gal res because im running 12 to 18 plants instead of 3.

How concentrated to make Nutrient Solution in my 13 Gallon RDWC Reservoir for One big Plant?

I am modifying my Power Grower RDWC systems to have a 13 Gallon Reservoir. And in general my tendency has been to make my PPM stronger then what they actually consume nutrient wise! I have done this because they don't seem to burn and because they can consume the whole entirely of the reservoir in one day at their peak flowering cycle. In Veg my plants can drink as high as 1400 PPM which seems crazy. But as soon as I flip the light cycle this drops to about 600-700. .5 conversion And I...
