I like what I see:thread:, it all seems very familiar to what I've been seeing lately.
My advice is maybe the plants aren't getting enough of full sun light throughout the day,... Perhaps.
It's possible to tie back some of the local branches near your patch back with something like para-cord or train the sun blocking/canopy above out of the way. ""this is all in theory that there is/or could be other plants/vegetation block the sun from your own""
I like seeing the bat guano, good stuff.
Try adding a bit of some stuff like Myco Madness or Great White Premium Mycorrhizae + ben. Bac & the controversial Trichoderma
and humic acid.
Do this and you should see a bumper crops, this the method I'm just now starting to use.
The humic acid, Mycorrhizae/s, Bacterias, trichoderma will all help the roots get the good food they love.
There is a lot of talk about the Trichoderma causing problems with the different types of Mycorrhizae, and many are talking about no longer using Plant Success products such as "Great White, Orca, and others". I use Great White + Xtreme Gardening Mykos 30, but maybe using Humboldt Nutrients "Myco Madness" would be more preferable.
