Healthy cannabis plants don’t need more nutrients.
They need balance.
If you understand pH and EC, you eliminate most beginner problems immediately.
pH measures how acidic or alkaline your water or soil is.
Cannabis prefers:
Soil: 6.0–6.5
Hydro: 5.5–6.0
If pH drifts outside this range, nutrients become unavailable. This is called nutrient lockout.
Even perfect feeding won’t work if pH is wrong.

EC (Electrical Conductivity) measures nutrient strength in your solution.
Too low → slow growth
Too high → nutrient burn
Seedlings require very low EC. Flowering plants tolerate higher levels.
Feeding must match the plant’s stage.
Overfeeding
Ignoring pH
Not adjusting nutrients during flower
Adding supplements too early
Precision feeding builds dense, healthy plants.
Balance beats excess every time.
