@MuddyWater, I see that you water at ph6.0. You could try flushing with plain water at a little higher ph, like 6.5, and about 3-4 gallons of water to flush out any salts that may have built up in the soil. I wish you best with your grow.

@MuddyWater, or it could be just on a cold floor. I've had some that point down let that over the roots getting cold. I just put something under them to space them away from the floor.
