Based on advice received here regarding severe and rapid browning of leaves, cleaned out DWC Oxy Pots and started again with a considerably weaker nutrient solution. EC down from 2.0 mS/cm to about half that. Also brought PH down from the level of local water, ~6.3, to 5.9, using a few drops of PH Down (acid). Swapped to a more powerful 4-hose air pump, one air stone in each DWC Oxy Pot, the other two in a run-off reservoir I use for four coco/pebble grows. Now let's see if the browning stops, and whether there is a noticeable effect on growth rate...
