The only thing I can think of is there is always more crap in the box than in the rez. If using Tron you prob get small paticles of it in the box which could and most likely does effect the PH in such a small area. When your system floods take a reading at one of the buckets when it is full and you will know what the plant is getting tits on :jointsmile:
