500 ppms of calcium is way to high for cannabis. I only use
from the web what I personally agree with, as it saves me a
shit ton of one handed typing. That being said, here it is:
500 ppm of calcium in a hydroponic system is way too high for cannabis and can cause serious problems, including:
500 ppm is overkill and will almost definitely result in nutrient lockout or toxicity.
If someone’s running that high, they should dilute their nutrient solution immediately and aim for a more balanced feed. Let them know before their plants start screaming!

500 ppm of calcium in a hydroponic system is way too high for cannabis and can cause serious problems, including:
Nutrient Lockout:
- Excess calcium will block the uptake of other essential nutrients like magnesium, potassium, and phosphorus.
- This can lead to deficiencies even if those nutrients are present in the solution.
pH Imbalance:
- High calcium can raise the pH, making nutrients less available to the plant.
Symptoms of Too Much Calcium:
- Stunted growth
- Rust-colored spots on leaves (often confused with deficiency)
- Leaf tip burn or curling
- Salt buildup in the reservoir and around the root zone
Ideal Range:
100-200 ppm is ideal, and pushing above 250 ppm can start causing problems.500 ppm is overkill and will almost definitely result in nutrient lockout or toxicity.
If someone’s running that high, they should dilute their nutrient solution immediately and aim for a more balanced feed. Let them know before their plants start screaming!
