1stGrow-Cheese & Super Lemon Haze Autos

Week 4 was a fun week. They've really started to grow! LST training, although stressful the first time, wasn't nearly as bad on the second go. This is a concept that is new to me when it comes to cannabis. I've seen it with bonsais and stuff, but this really gave me a new perspective on how to grow and maximize yield etc... It is also a really good intro into parts of the plant, because you get an idea of what parts of the plant are important and during which stages. Otherwise the week was simple. The tent has been maintaining temperature and humidity almost perfectly since I rearranged the grow setup, my only one worry is the small amount they are drinking. Comparatively, from other photos as this stage, they seem to be doing quite well, but they each only had 4 cups of water last week (2 with nutes and 2 without) As I've mentioned previously, I don't want to overwater, so I have been stretching it a bit, but is this weird?
