PH keep rising in DWS, RO water?
LiberFelixstarted grow question 4y ago
I use tap water (soft water), Canna Vega A/B and related products, with rockwool.
PH is stable around 7.2 - 7.5. I PH down to 5,5 and 6-12 hours later its back up. This is my second rund and had the same problem then.
Could reverse osmosis water help this, or other advices?

Plastic grow bags. What's the deal?So I'm using plastic grow bags. They seem to hold moisture a lot more than fabric grow bags.
Might have to cut more holes in them or just use them for transplanting clones or something.
Anyone use these? What are they good for? Suggestions?Week 4

I just gave some Canna PK (25 days since 12/12). Is it too early ? Bruce Banner 60-65 days of floweringClosed irrigation hydro system with clay balls. If it is too soon, will I have issues ? And what PH do you use ? I read it should be 6.3-6.4 at this stage but Canna advises 6.2 max. Thanks !Week 8

Hydro - Ec stable, Ph dropping - Raise EC instead of lowering it ?I have the feeling that when there's not a lot of nutes, PH drops but it means I have to add EC, not lower it. I noticed this when I fed them with a very low EC. I added more EC and they ate a lot right away. What did you experience ? Has to do with them eating all cal-mag ? THXWeek 7

Adding DWC nutrients during the week?I flush & add nutrients once per week, and I can't seem to find specific info on adding additional nutrients during the week. Say I start with my basic ratio for the week, and by mid-week, the water is lower. Do I use the same ratio for 1 more gallon or just one specific nute?Feeding. Other
