PH keep rising in DWS, RO water?
LiberFelixstarted grow question 2 years 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?

I also use tap water, when you PH it its best to let it sit overnight or aerate it. this will help even out the ph range and keep it more stable.
for my tap water I need to add in 9 drops of phosphoric acid and bubble for 2hrs to get to stable to 6.7.
if I do not bubble/aerate it. 4 drops gets me down to 6.5 but it does not stay there for long.
Every city/towns tap water will be slightly different got to experiment whats best for you.
Also RO water would take the waiting time out of it. its just a lot of extra money if you don't have a system installed yet.
Good Luck!

Questions about wateringI created a 40 ml solution, the instructions say to transplant after the sprout has grown to the top of the plastic cover and the roots are visible through the plug. The question is, is 40 ml of liquid enough for this growth? I think not.

Feeding right after repotting (coco coir).After repotting an auto flowering plant I get runoff EC of 800, while feeding water has EC 1200.
I guess EC gets diluted (biggest part of coco coir is new).
Should I increase EC of the feeding water?
I see slower growth but it may as well be due to stress of repotting.Setup. Strain - Autoflowering

expert opinion asked ? Maturity in day 49 flower from 60-65 (according to breeder)Maturity in day 49 flower from 60-65 (according to breeder)
I'm not sure about the degree of ripeness.
I used Co2 for a few weeks (1000ppm), the grower says ~60-70 days of flowering, so I would be missing 10-20 days, but they look quite ripe ?
What should I do
Thank you
