Thats one of the reasons I suggested using RO and CalMag vs bottled water. But I am not seeing an mg def there and I dont think you need to go higher. If you do.....watch carefully for overnute.

I'd still love a photo of the entire thing.....it would help a lot.
Weedhound Reviewed by Weedhound on . DWC Plants seem to be becoming sick Ok my plants seem to be beginning to drop and some kind of deficiency. Ok a couple questions if anyone would be so kindly to help. I have a couple dropping leaves toards the bottom of the plant anything I can do about that? Also As you can see in the pictures like 1 or 2 leaves out of all 5 plants have those yellowish orange spots which doesnt make sense why wouldnt other plants show signs?
