Hello. This is my first time starting seeds in rockwool cubes. I planted two seeds in RW watered with ph'd water to 5.5. After germinating one looked purple. When I woke up this morning bother were drooping and purple. Anyone know what's happening. My temps are around 70-78. First time with RW I useually germ in soil but this will be my first dwc.
