These pH affecting products are universal for gardening and can be used on almost all plants in your garden, not just your cannabis. Keeping a correct pH in your cannabis plants’ grow environment helps prevent nutrient deficiency that can stunt growth and result in a lower yield of marijuana buds. The cannabis plant prefers a slightly acidic pH environment of about 6-6.5.
When the pH environment rises in alkalinity above 7.5, the roots of the cannabis plant are not able to consume the available iron, copper, zinc, and manganese in their vicinity. When the pH lowers into an acidity of less than 5, the roots are not able to access phosphoric acid, calcium, and magnesium because they lose their solubility. Correct pH allows the cannabis plant to properly access nutrients in its soil in order to grow its best. When setting up your garden to grow cannabis, it is always best to conduct a simple test to determine the pH identity of the soil and water. Improper pH can keep the plant from growing as healthy as it could be and can affect the ultimate levels of cannabinoids and terpenes in its flowers. Proper pH can also affect how large and how quickly the plant can grow. If soil is alkaline, adding compost to the soil before the growing season will add nutrients and make the soil more acidic.
The pH of soil can also be affected while the plant is growing using pH up and pH down products that are applied when watering your cannabis plants. You can test the pH of both your water and soil using commercial pH tests to ensure your cannabis plants are in the best possible growing conditions. Add nutrients to the water that you will feed your plants. Test the water you will give your marijuana plants and adjust pH accordingly, aiming for a pH of 6. To also test the pH of soil, test early water runoff from soil after you water your maijuana plants. If runoff pH is… in the right range, no changes or additional steps are needed. too low – provide next watering at pH 6.5 – 7 Too high – provide next watering at pH 5 – 5.5. Healthy, happy cannabis plants create the highest quality buds. When marijuana plants are able to absorb available nutrients in their soil, they can grow tall and strong and generate the high cannabinoid and terpene content you’re hoping for in your buds. This can be accomplished by keeping the soil and water with which they are grown within an ideal pH range for the cannabis plant. When the pH of a marijuana plant’s growing conditions falls outside of its normal, ideal range and nutrient deficiency begins, you will begin to see signs that include yellowing of leaves, brown spots on leaves, and dropping of leaves. Plants suffering from nutrient deficiency can also be more susceptible to pests and disease and can experience reduced flowering. If these problems persist, even when you have an ideal pH in your garden, then you may need to add nutrients like potassium, nitrogen, and more to your growth medium through a fertilizer.

In the month I have been on roll it up, I have read countless threads of plant problems, dark green leaves drooping, claw like looking, slower growth and purple stems to name a few. High ph is problem for many growers including my self. Here are a few plants that are healthy, growing fast hell, and the ph is right around 6.5-6.8 range. View attachment 2930066View attachment 2930067View attachment 2930068. I selected a few plants that I dont really like to do this experiment on. Here are the pics of the root systems before the experiment. View attachment 2930071View attachment 2930072View attachment 2930075 They are healthy, white and very fast growing, this is after 4-5 days after my second round of transplanting.
With-in 12 hrs of flushing with 8.5 water the plants started showing symptoms, drooping, claw looking leaves, dark green and almost a 3d look to the leaf surface. There are some leaves that curl and twist as the soil is now toxic to them.

After 48 hrs the ph continues to lock out nutes and makes it almost impossible to tell what the hell is wrong with your plants. If the ph remains high for more than 48 hrs it will start yellowing the plants and make them look like death( note if the ph is around 7.5 the yellowing will take much longer and the dark green leaves and drooping will be the main symptoms) When the ph is above 8 it locks out many macro and micro nutes at the same time which causes the yellowing, brown dead spots, rust color spots, purple leaves and stems and many more symptoms.
