hey Ko ,i said the EC would rise as it was a fresh res & it usually rises a bit in the 1 24hrs while all the nutes disolve ect...
by the time i had added 6ml cal/mg & 30ml of rhizo, the res was at around 350ppm & it only took 8ml of A&B to get upto 525ppm (just over EC1.0)
I probably only have 13.5-14 ltrs actually in the bucket ...... Are you saying that it should take more A+B to get 1.0 ???....EC has stayed the same untill i added some water with sillica to up the PH & then it dropped as its been diluted ... wouldnt the Ec rise as well if she was only drinking ??
