Hi
Currently I’m in mid flower with a couple of autos (1 x FB Blue Dream, 1 x Zam Bluberry).
This is my 3rd grow but the 1st time I’ve tried living soils.
Indoor grow in 20l pots, with LED lighting. limited space as it’s a setup at home and it’s still illegal in my country.
I have many questions but I’m trying to learn from the information already here on the forums so I don’t piss people off asking things that have already been answered.
However, that said I do have one I can’t find a concrete answer for.
Is there an issue with using rain water with living soil under LED light?
I know my plants have some deficiency’s and from the info gathered so far I think it is just because I followed the directions for my dry amendments but too late or the nutrients in the soil just ran out quicker then expected.
BUT….. while frantically trying to diagnose my problem I found a thread on another site that said something along the lines of
“rain water isn’t good with living soil as the TDS ppm is too low and the plant can’t take up the nutrients”
Supposedly it’s similar to RO water in that regard and you need to raise the ppm’s with something like cal/mag to around 400ppm.
But then adding cal/mag to the rain water could have a negative effect on the microbes in the soil.
I’ve got myself all confused
. If anyone can shed some light and maybe explain the science behind that idea (if it’s even true?) I’d be eternally grateful.
Whew that was long winded…..
Thanks in advance
