Hi everyone, this is my first grow. I’m on Day 15 (5/14 early veg) and completed a drain/fill yesterday afternoon.
Since the drain fill I have heard the noise of the nutrient bottle pumps and have noticed the levels in bottle #1 and #2 have changed but nothing has changed with bottles 3,4,5. After my first drain and fill bottle #5 did dispense but it hasn’t ever since.
I checked the tubing from the bottles and they all look ok. Any idea what is going on?
