you might run your feed-lines into a 'ring' that encircles the plant, or just stick them into the hydroton, to minimize splash ... I wouldn't worry too much about the 'distribution' of the solution, the roots should seek out what it wants, I would think ... (all that white stuff is baking soda residue, when I was using it for pH adjustment, you can see it makes a mess, not recommended) ... I'm no expert, only on my 3rd hydro grow, so take that for what it's worth ... good luck ... :jointsmile:
