So week 5 is quickly approaching and I noticed I obviously over nuted the plants. The pH was WAY to high for some reason and I'm looking to lower it. Are all signs that don't look healthy in the included pictures symptoms of over-nuting. I know for a fact it isn't lack of light or over watering. The run off is also a tanish, brown color. When I water the plants I give just enough to where some drops of water begin to fall out of the drainage holes and collect it for testing. Anyway, take a look and tell me what you think. They are all about 4 1/2 weeks old. Also if you have any thoughts as to what type these girls may be feel free to post thoughts. They are all different shades of green, and although all were planted at the same time, one is GIGANTIC! You can't tell in the picture but it's about 2 to 2 1/2 feet tall.
