3-4 nodes and i water according to weight and how long since last watering, the only things i can tell you about my water is that the ph is around 7 and it comes from the tap. i have not added anything to the water. sorry i cant get pics but i will describe my current plant best as possible, leaves are somewhat wide, first 2 sets of leaves yellow next leaves still green but feel very crappy like paper almost and they dont smell good (amonia). i know it is possible to grow a plant though flowering with this water but i was only able to accomplish this using a crap brand of seedling soil called CIL which of course i can no longer find
