Not sure, but I would think you would see more deficiency symptoms other than drooping if it were the nutrients. Your container might not have sufficient drainage. What does it look like underneath? Just one hole?
Does it stay outdoors?
What kind of soil are you using?
How far along are they?
How often do you water? (soil looks wet, could be overwatering)

As far as nutrients, it depends on what you have nearby. Hydro stores, garden stores, big box stores, no stores? Online will definitely have EXACTLY what you need. Don't be scuurred of ordering legal gardening products over the nets :thumbsup:

So... yeah... people are going to want some more basic information. There is a troubleshooting form that will cover all of the info to help people give you an accurate diagnosis.

If you don't want to fill that out, at least answer the questions I posted and that should get ya started.
Plant looks :thumbsup:, as far as I can see... just a little droop on the stoop.
Be easy :jointsmile:
