So you go Full Board with it.. Are you putting it in before your micros/nutes?I run dtw coco/perlite at 5 +/- ml a gal

Take your res to 160 to 200 ppm higher than your base water.HI ALL!! I just Transplanted clones into my RDWC and will be using Advanced Nutrients M,G,B. I recently purchased a small 100gpd RO unit, and wanted to get some opinions on how much CalMag I should be using??
Any info on this one would be very helpful :)
I use 1 ml per l cal mag with 1/4 ml per l rapid start using purified water 80cents per gallon ( only got 5 going ) ppm 550-600 in veg super soil new so not using any grow bloom or micro yet prolly start I. A week or two any thing u guys would change or does it sound good ?The first thing you should do is add 20% water to your RO this helps keep Ph stable. I use cal-mag at the rate of 1 ml per liter. of 4 per gal. RO is notorious for playing havic with your Ph due to the water containing nothing.
Here is a great tip for those who use reverse osmosis water to buffer your water and help stabilize pH. There are two ways, both efficient.
- For those who prefer simplicity, all you have to do is add 20% tap water to your reverse osmosis water.
- For the purists who do not want to use tap water, or whose water is particularly bad, here are two easy steps:
1 – First increase your pH up to 10.0 with pH Up or potassium carbonate
2 – Then bring it down to 6.0 with pH Down
In both cases you’ll obtain water well adapted to hydroponic nutritive solutions, while avoiding untimely pH fluctuations.
You need to raise pH first because the “buffer” elements have a very high pH or very low pH. You can start by adding acid, but then you will need pH up to raise your pH.
You need to buffer R.O. water simply because pure water has no buffering capacity. It is subject to big swings in pH every time you add something to the solution, making it unsuited for cultivation. Using pure R.O. is a classic source of failure.
If you’re using reverse osmosis water, add 50-100 ppm of Cal/Mg; this helps to buffer your water so nutrients absorb better. From Advanced Nutrients site http://www.rosebudmag.com/hydroponic-tips-ideas/insider-tips-for-maximum-yield-in-urban-garden
