Hey Vanessa, no need to feel silly! Before you do anything, please make sure you have the latest EasyBloom Companion installed. Point your browser to http://easybloom.com/go to download the latest version (it was last updated on Thursday, April 15th). When you plug in your EasyBloom Plus, the new companion will recognize the new fertilizer capability and pull up a subscription option when it launches the website. If you choose not to subscribe at that point in time, you can always opt in later at the My Profile page. Hope this helps! Regards, Noam / EasyBloom Support
