Muggles Posted October 23, 2002 Share Posted October 23, 2002 to get my pH down to 5.7/8. I live in a hard water area (south coast), so I'm using Canna vega 'hard'. Will having to use this amount of pH down affect the uptake of certain nutrients, and, if it does, how can it be remedied? Thankyou in anticipation I've finally gone live, again... :o Link to comment Share on other sites More sharing options...
KC Posted October 23, 2002 Share Posted October 23, 2002 Hello there, just wondering what type of pH down you are using. I hear that phosphoric acid affects the nutrient uptake more than nitric acid does, as for why i have no idea and i'm sure someone will know alot more about it than myself. Been awhile since i did any chemistry...seems like a million years ago (although it's only about 6 years) but i don't think i was paying attention anyway Hope that helps a bit. Good luck KC Link to comment Share on other sites More sharing options...
Muggles Posted October 23, 2002 Author Share Posted October 23, 2002 Cheers KC. I'm using phosphoric acid pH down. I'm sure I read the same as you, somewhere, ref: types of pH down having different effects. It's not terminal, I would just like to know Link to comment Share on other sites More sharing options...

hemp playboy Posted October 25, 2002 Share Posted October 25, 2002 I'll just chip in too - I live in a very hard water area - not far from you - switch to nitric acid - you put less of it in, to achieve the same results. As far as I'm aware there are not real changes in nutrient absorption - nothing that's alarmed me anyway - and as you use a lot less - I'd prefer less to be ending up inside me. (kinda) Growell - do a separate bottle of nitric - cheaper than phosphoric - and aimed at hard water users. tata hp Link to comment Share on other sites More sharing options...
Muggles Posted October 25, 2002 Author Share Posted October 25, 2002 Cheers for that hp. It was the wording on the label that had me concerned..."use sparingly". Take care Link to comment Share on other sites More sharing options...
