Ph question
Ph question

started grow question 2 years ago
When you buy spring water, how can the company say it's a certain pH if temperature affects this ? I'm struggling to understand how temperature affects water so much. Does the heat make ph rise or fall ?

Inversely related. So, temp goes up, pH goes down. increased H+ activity, therefore more hydronium formed on average in any 1 snapshot of time.

Questions about watering
I 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.

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

How to use EC meter Milwaukee CD611
I bought a EC Milwaukee CD611 tester and I don’t know how it works? With tap water + A+B it displays 11... I have a crop chart for autoflowering in which it is indicated in the line CE (Vegetative: 0.9-1.1 EC) How to match this chart with the numbers on the screen of the CD611?

tank feed
How long can I keep a mix in this tank. I must admit it does not smell good. The mixture smells so bad after a day or two and does it affect the plants in any way?
