4 strain seeds in soil

Plants are doing great. I bought a bottle of gaia green power bloom soil amendments and mixed it into the top of the soil. Hopefully this will keep the plants and the soil microbes well fed. It contains stuff like rock dust, bone metal, kelp meal etc. Seems like a good quality product. Wanted to try this as opposed to a liquid nutrient mix. The blueberry plant is by far the largest and most mature plant at this point. Its leaves are standing straight up and I can't figure out why. The temp and humidity is normal and the light can't get much farther away. It's not a powerful light to begin with. She still seems to be happy so I'll let her be.
