Just watering at this point... Lights and environment don't really seem to have any impact one way or another on vertical growth of this girl... So small... I've been keeping the temperature a touch higher to see if that helps and have her in a tent with a CO2 bag as well to see if that helps her in vertical growth and done a little bit of bottom watering to make sure the roots stretch... Waiting and watching...
Near the end of the week, I finally got a BlueLab pH tester as I feel as if my water has changed recently and I haven't tested it for a looong time. After testing I found the pH was INCREDIBLY high (8.8-8.9). This could explain the stunted growth. As I've just found out about this, I'm going to get some pH down in the next day or two so I can correct this moving forward. In the past my pH was always around 6.5-6.6 right from the tap so I hadn't ever needed my own pH meter in the past... Live and learn.
