First Grow - RQS Watermelon/RQS Critical

Girls are really starting to explode in height this week. Went with a 1-4-4-7 nutrient schedule and the plants seem to be taking it well. Been struggling with my VIVOSUN controller failing to read humidity and temp values from the external probe so at times humidity is getting super high, but I don’t think it will be a major issue as the dehumidifier seems to work well until it gets full but if I’m at work then I’m kinda screwed until I get home.
