Big Bud (Autoflower) - First Grow

After her first LST session last week, I have been regularly tying her down until the other smaller colas catch up. She is doing incredible, and the smaller bud sites have grown immensely since the start of her LST. Her stalk is thickening up nicely, and if you brush against her with your hand, you'll smell her amazing weed fragrance. On day 25 I gave her another nutrient feed. However, just as I finished feeding her, I noticed a little nutrient burn on two of her bottom leaves. So I am a little worried that I just gave her another load. I'm sure she'll be fine, I'm just going to keep an extra eye on her. On day 27 I watered her with plain water.
