No, not completely lol.
But based on some input from Ganja Guerilla in
http://forum.grasscity.com/sick-plan...dro-setup.html I've learned that simply topping of my reservoir with new nutes per the Lucas Formula does NOT work unless the reservoir was originally started out with the Formula. Despite the fact that my ppm's were about right, my nute ratios were out of wack and my darlings all developed a significant phosphorus deficiency.
So today I had a wonderful time completely draining my reservoir and refilling it with the correct nute formula. I actually wanted to do it yesterday, but Murphy's Law struck. Yesterday was the first Saturday in two months that my roommate didn't go into work lol. Fun times, I'll tell ya.
Also, the new plant that I added to the hydro unit to replace the non-thriving plant has also shown some really slow growth. Since both plants are in exactly the same slot on the tank I suspect that the issue may be related to my set up rather than the plant. Ganja noted that my system was splashing nute solution directly onto the leaves and suggested that this might be causing the slow growth. The drip tube has been repositioned and I've arranged some clay pebbles around the opening of the tube to act as a water break. Hopefully this will get the little girl going again.
