Yes, sounds like a def. If you use RO water you should also use CalMag+ to help replace lost mineral like calcium etc that the RO system takes out. Tap water usually has these minerals already.


Why did you switch over if they were doing well on your regular water? Or was there an issue?

PS Do you mean your tap water is at 150ppm? Never heard of tap water at 1500.

Also what is your humidity level? Fungus problems seem to be going around this time of year.

If it ain't broke, don't fix it.
I am having a hard time understanding why you made the switch.
If I were you I would go back to tap water immediately. Adjust the pH to 6.8 and do whatever you were doing before when you say your plants were fine. At this point, if you think you are having a deficiency, why would you flush even more?
