Photosynthesis Plus & Seaweed for the Pumpkin Plants

This evening I did a application of Microbe Life's Photosynthesis Plus with two tablespoons of seaweed on all of the plants.  Photosynthesis Plus has Rhodopseudomonas palustris and Rhodospirllium rubrum in it (don't ask me to spell either of those on a spelling test) which are some pretty interesting bacteria.  I got this product for free and thought I would give it a try.  I've done two applications previously with it added to my compost tea.  I can't say if it made a big difference but it didn't kill the plants.  In addition to the previously mentioned bacteria it also has a number of other beneficial bacteria and fungi in it.
