Oh man I've written out the explanation for that like 5 times in the last week... okay here goes. Drinking water (bottled) has minerals added for flavor, and higher sodium than you want. Tap water would be more likely to contain calcium and magnesium and lower sodium. Plants need Ca and Mg.
If the tray is attached, remove it from the pot, otherwise, you're good to go on that.
Your pH sounds decent; using tap water will help keep it that way.
stinkyattic Reviewed by stinkyattic on . brown/yellow spots on lower leaves my plant is about 4 weeks old. the other day i turned off the small fan i have in my box. i sprayed the plant with some water and left it alone for a day, next time i visit it i notice these brown spots on a few of the lower fan leaves. at first i thought that because i sprayed water it might have puddled on the larger leaves and with no fan to help it evaporate, maybe it just sat too long and caused the lights to magnify and burn the plant, but after turning the fan back on, i haven't misted Rating: 5
