Aero update: trimmed the roots that reached the water, about 2 inches cut off. Roots still looking healthy from what I can tell. Tops are growing better and look healthy. Ph was 6.8 when I checked today, brought it down to 5.5. They seem to like the range of ph I have been allowing. I ordered a circulation pump to keep the res water and nutes mixed.
Little sprout pushing out from the bud looks like a seedling
