Autoflower Grow #1

I took the weekend off and was out of state. When I came back today I found that most of the plants have gotten thicker. I noticed on the thin mint crack that didn't have the mirror fell on was infested with some some white bug, possibly spider mites, I ordered some lady bugs from amazon to combat left over pests. I also found a caterpillar nested inside one of the lower bud sites. I removed the afflicted bud site and called it a day. They are due for a watering so I'll give them another dose of cal-mag. The fading of the leaves was pretty noticeable after being away for a couple days away I don't know if I should be worried about it or not at this point in flower. They are still chugging along nicely so I'll probably leave it. Ak420 is not pictured, it's still doing its thing, just outside. It's not any where close to as dense as the ones in the tent.
