soooo...you are saying I should go till the concentration roughly equals my water??? I thought it necessary to refresh each week, or even sooner(according to an article in Maximum Yield)...I wondered about the make up of the remaining nutes, is there an equal proportion to the starting formula??? what about just topping with a like concentration of the starting nutes, I thought the balance could be off...Not to be cheap or anything, just concervative...
