Flushing With Ro Water

[saltwater]

So usually I add cal mag to my RO water .

I use 4stage RO unit.

My plants are in what I believe to be their last few weeks in flower. When flushing should I use RO water mixed with calmag or should I just flush with pure RO water no calmag?

Sorry for the noob question. This is my first grow and I can't find legit information.

Thanks all.

I use a lil bit of molasses and ro the first time maybe twice then just ro water the rest of the way.no sense wasting calmag during flush unless your trying to keep them growing.

Good point, that's what I figured. Thanks for the comformation!

You could just use tap water also as long as its not terrible.but i like the outcome using straight ro.gl

i would definitely use calmag

If you use molasses like sixstring does there is cal and mag in it.
