Finally had time this weekend to work on everything. Filled my dwc system last night and had some small drips so I emptied it silicone sealed everything and let it sit to cure. Will fill again tonight and see if that has helped. Here are the seedlings as of this morning.
The big plant is doing OK still. I burned it just a little but so I flushed (light flush as it was light burn) with distilled water. PHere of Runoff was 6.4, previous reading was 7.0 last week. I'm also fairly positive it's suffering a magnesium deficiency. Purple stems among other things. I'm going to foliar feed using epsom salts during lights off then add some Mag-pro later this week once the soil has dried again. Roots are exploding out of the drain holes in the bottom and all are healthy white.
