Blueberry Big Devil Auto First Grow!

Allshtee I have four plants that were planted in soil on 3/21 after germination. This is my first grow so I thought I would just keep it simple in some Foxfarm Ocean Forest Potting Soil, I haven't added any nutrients yet but already have the fox farms trio and some calmag. I am having trouble keeping the humidity up as I live in a pretty dry place, so I ordered a small humidifier in hopes to not have to mist the walls of the tent every few hours. I topped two of the four just to see what kind of differences it would make. If anyone has any suggestions, please feel free to comment! I know there are many other or better ways to grow and am already reading into all of my options, but very open to feedback and help of any kind!

Allshtee These plants are doing well, and they started to flower! Around week 3 or 4 I started to see yellow / brown spotting on some of the new growth, I added some CalMag every other feeding and that small amount seemed to do the trick as the new growth is pretty healthy. As of the most recent feeding I added a very small amount of Fox Farms Big Bloom, I don't want to overdo it. Been busy otherwise so not many updates, but I am having a great time for my first grow!
