R.o. Water And Cal/mag Question

[Space-Man]

If I am using R.O. Water, should I be using the Cal/Mag Supplement with every watering and feeding?

 

I really don't have much of a feeding schedule yet, it's been as needed until I can dial it in.

 

Thanks!

I use only when plain watering. That's is what i was told. 5 ml per gallon.

Thanks for such a quick response! I really appreciate it!

Add Cal/Mag everytime you water.

 

The Cal/Mag helps with the pH and reconstitution of the water.

What are noticeable Cal/Mag deficiencies?

Yellowing around the edges, browning spots, curling in latter stages....usually starts from the bottom

Very informative link, I also read Cervantes' Indoor Horticulture but felt like needing more info.

 

I definitely had a Mag def...it was only one leaf so far on the bottom that was yellow, burnt looking.

 

I've been using Humboldt Nutrients Natural Grow and Bloom. I did not know about using Cal/Mag with R.O. water so I feel pretty bad for my girls. But since I caught this early, and now that I'm treating them, they s/b fine.

I dont have the cal/mg prob with R/O but I do use micro every feeding,I have seen some signs on a bubba I have in dirt but thats the only 1 thats acting up-my hempys and bubbles are fine and my girls in dirt in veg are fine but maybe the girls in dirt in flower need the extra cal,mag-ill see when I feed
