I let my water sit in gallon jugs with the cap off for at least a day to dechlorinate it(sometimes a lot more). Last time I watered the leaves started drooping slightly, and it's definitely not from over watering. Soil was bone dry two inches down, 16 oz cups with ffof and %20 perlite. Could it be because the water was oxygen depleted.? Couldn't one just vigorously shake a jug of water 3/4 full, just before feeding, to dissolve enough oxygen into it?
