Day 21 and the girls are looking nice! I added mylar to the walls, mounted a bigger fan to the wall above light for airflow and to keep the light temp down as I start to increase the PPFD. Made a scrog net when I had some spare time. Some plants are growing faster than others and I want to try and have an even canopy. I gave them the first very, very, light feeding of Advance Nutrients Sensi Grow A&B, Bud Candy, Nirvana, B-52, and Sensizym on Sunday. They seem to like it!
