Beary White Mephisto Genetics Autoflower

I had another week of very minimal veg growth, which doesn't seem to hurt my spirit as much as I thought it would. This slow growth might be because I haven't given the plants nutrients as of yet, or this is because of the lack of humidity in my grow space. I felt very positive with the first couple weeks of seedling growth, but now I'm not sure what happened. I've compared everyone else's 28-day old from seed plants and I realized that mine are not quite cutting it, and this is going to mess with my abilities to LST them when they get a little bigger. I'm going to give them their first nutrient feeding tomorrow and I hope that with the added supplementation that they begin to explode with new growth.
