ph : Hydroponics Plants Problems and Solutions

What is pH?

pH is a scale from 1 to 14 that measures acid-to-alkaline balance. One is the most acidic, 7 is neutral and 14 is most alkaline. Every full point change in pH signifies a 10-fold increase or decrease in acidity or alkalinity. For example, soil or water with a pH of 5 is 10 times more acid than water or soil with a pH of 6. Water with a pH of 5 is 100 times more acidic than water with a pH of 7. With a 10-fold difference between each point on the scale, accurate measurement and control is essential to a strong healthy garden.

Cannabis grows best in soil with a pH from 6.5 7. Within this range, marijuana can properly absorb and process available nutrients most efficiently. If the pH is too low (acidic), acid salts bind nutrients chemically, and the roots are unable to absorb them. An alkaline soil with a high pH causes nutrients to become unavailable. Toxic salt build up that limits water intake by roots also becomes a problem. Hydroponic solutions perform best in a pH range a little lower than for soil. The ideal pH range for hydroponics is from 5.8 6.8. Some growers run the pH at lower levels and report no problems with nutrient uptake.

Method for Adjusting Nutrient Tanks
This is the correct order.

* Top up your tank with water first
* Test your nutrient strength
* Raise the strength by adding equal amounts of A and B if necessary.
* Now test pH

* Adjust pH with pH Raise or pH Lower. Dilute* the pH adjustment solutions as directed on the labels.

* Concentrated adjusters are so acidic or alkaline that if used in a concentrate there will be a reaction with the nutrients dissolved in the tank. This can imbalance your highly formulated nutrient.

f testing both Nutrient Strength and pH, the nutrients are still best changed each week. However, Nutrients need only to be changed on a fortnightly to four weekly basis if desired.
The more often you change your nutrients, the more ‘balanced’ your solution will be. But as you will be adding nutrient as you go, the nutrient balance does not become as critical as it does without adjustments.
