Ph question
Newbie87
started grow question 3y 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.

How to Use Fulvic Minerals?
Organoman mentioned using Fulvic minerals a few days ago. How do you use them in soil? Do you apply a small dose with each watering/fertilizing or is it something you do only once or twice during the grow?

Optimal pH
Is it more important to measure pH of soil or of the water/nutrients used for feeding? Or both? If so what’s the optimal pH? Thanks!

low pH problems
I discovered that I had irrigated with water at pH 3.5 for at least 5 days. yesterday I used water at pH 5.7 and today I think it will increase to 6, but I noticed that burns are already starting to appear so should I continue like this and hope for the best or do a root wash?

Watering in Super CoCo
Hey there fellow growers! So I’ve been trying to figure out the best watering schedule and volume 🧐I’ve been told to always water with runoff, go by weight, top inch dry, etc. I guess my main question is runoff necessary when watering in Super CoCo? All advice appreciated!🌱

EC in 1200/EC out 596?
I continue to raise the EC to as high as 1200. But the runoff EC is around 590. Am I to up the input to 1400 now to compensate? Seems extreme. The plants are doing well other than slowness.
