Cannabis, like many plants, prefers slightly acidic soil conditions. It tolerates a wide pH range (5.0-7.0) without symptoms of bronzing or interveinal chlorosis (yellowing of top leaves), but pH levels outside of the optimal range of 5.8 – 6.2 will limit growth.
What is the best pH for cannabis in Coco?
Acceptable pH Range for Coco: 5.5-6.5 During the majority of the grow your inflow pH should fluctuate around an average of 5.9. However, during the seedling and ripening phases it is best to target somewhat higher in the range (6.1-6.3).
How do I lower the pH in my cannabis plant?

What soil pH do tomatoes like?
6.2 to 6.8
Tomato plants will grow well in well-drained sites that receive full sun for most of the day. The soil pH should be slightly acidic (6.2 to 6.8). Excess nitrogen can result in plants with lush, vigorous foliage but little fruit production.
Does perlite affect pH?
Perlite is crushed aluminum-silica volcanic rock, which has been heated rapidly to very high temperatures, during which process it expands to a lightweight, chemically inert, and sterile material. Perlite has no nutrients, and with a pH of 7 to 7.5 (neutral) it does not contribute to the substrate pH.
When should I feed my cannabis seedlings in coco?

The plant could be growing where it is too wet or too dry or could need additional nutrients, such as nitrogen, sulfur or iron. However, rhododendrons, azaleas, blueberries, heathers and hydrangeas typically need a strong acidic environment, and if the soil has the wrong pH, are unable to absorb nutrients.
Can vinegar lower soil pH?
Vinegar Basics Vinegar is a diluted, liquid form of acetic acid, so adding it to soil naturally lowers the soil’s pH and increases its acidity.
Does perlite change soil pH?
