Marijuana Fertilizer Usage
Bergman's Plant Food is designed for correcting plant deficiencies and enhancing growing mediums. For best results, check for deficiency before using this marijuana fertilizer. Be advised, many growing problems are resolved by the proper amount of sunlight and water.
Always test your pH before adding Bergman's Plant Food. The ideal pH is between 6.0 and 7.0. Marijuana plants with poor pH cannot absorb nutrients and will impact your results.
Never give your plants more than they need. Overfeeding can lead to nutrient burn, which can harm your plants. For optimal flavor, flush your plants approximately two weeks before harvesting.
The nutritional needs of marijuana plants change as they mature; therefore, you must use a marijuana fertilizer that is appropriate for their development. View the feeding schedules below for usage guidelines.
