It turns out that the ppm level is around 1200 in my current setup...but the seedling seems to be doing alright for whatever reason....I will get it onto a proper diet soon, but i need to know one thing...my tap water is at 200 ppm naturally...should i buy the "micro hardwater" to compensate for this? I was thinking yes, but I am not sure.
one more question...
should i ease the pH up to the right level or should i do it all at once?
