I think I might have figured out what's going on. I tested the ph of my water and the ph of my water with my nutrients mixed in. The water by itself is at 8 and once I mix the nutes in it's at 5.5. So I have been following the fox farm feeding schedule and feeding every other watering. I water basically every 3 days, so every 3 days the ph is fluctuating in the water I give the plants. I ordered some ph up and down and I am going to start adjusting the ph of the water to 6.3 every time I water/feed. What do you guys think about this plan? Do you think I need to flush first or just start adjusting?
