First Grow Ever Notes: Seed broke soil on 8/11. Have been giving water when the soil looks dry on top, and trying to keep the humidity in the 70% range. The humidifier is running out of water early, and when the lights go on there is low humidity which is why the pics have humidity in the high 50s. Did not include any amendments this week, but plan on using Cal-Mag and Fox Farm Big Bloom next week. I have been PHing the water to 6.4-6.6, but have not been apply that much water. I am hoping that the feeding will provide the lower PH going forward.
