Hydroponic Nutrients FAQ

In this section, I will cover questions on primary nutrients, the use of additives (like B1), questions about pH and nutrient strength, how often to change your nutrient solution, flushing your plants, chemical fertilizers vs organic, what to feed your seedlings, how to adjust the feeding plan as your plants mature, and any other questions you may have related to feeding your plants properly.

The answers to many questions can be found at the bottom of this page, and also at the links below....please check them out before you ask your question. For general information on maintaining your nutrient reservoir, check out the how to grow hydro page. More information on nutrients and additives can be found on my hydroponic nutrients page. Finally, you can find some nutrient strength guidelines within the following pages....

Do You Have a Nutrient Question?

Using nutrients properly can be tricky. The needs of every plant are different, and those needs change as they grow. Once your garden is started, however, unanswered questions can become horrible, nagging problems that prevent you from getting the results you want! Feeding your garden properly is one of the keys vital to your success. Drop me a line and tell me your story....my experience can help you avoid or fix your nutrient problems.
