CalMag and Thrive in bloom...

[stinkyattic]

....Im using ro water in soil just now and man is it giving me a sore head i cant seem to get it right ...Is it possible to grow trouble free in soil with ro water?....

Sure you can do it.. you just have to WANT it hard enough lol!

I presume ( correct me if im wrong please) that my soil has calcium and magnesium already added and my canna nutes already have added cal +mag so unless i know the pecentages of the cal mag in the soil i will never get it right?HELP LOL.

I'm not sure if those elements are already added to your soil but they should be present at some level... have you considered supplementing your soil with a bit of bone meal? That's a nice slow-release Ca source, and Mg problems if they still arise are SO easy to diagnose and fix quickly!

My tap water run out at pH 7.2 and ppm 100 and after 24 hours getting defluorinated and airiated it comes down to 80 ppm pH 68 ...

Well with tap water that nice, I'm not sure why you would really even bother with RO in soil?

what is the benefits of using ro in soil i know the hydro benefits but in soil i cant see that it helps with weight..

The benefit would be the same as hydro: CONTROL. But IMHO the best way to have control over a soil grow is to have control over the soil itself. You can make your job of watering/fertilizing as easy or as hard as you like just by adding and subtracting soil components!

any help would save me getting stresssed and keeling over with a heart

attack....[/QUOTE]

And we certainly do not want you to have a heart attack!

Superthrive at germination/early veg, is fine.

I am VERY VERY careful of using superthrive too early, as you can definitely hurt seedlings with it. I pretty much wait on everything until it's time to feed anyway. Then again, my soil mix is on the hot side, so if your soil is very very mild, it might be fine.
