Long Loads & Erratic TTFB

[Islandspark]

Hey guys,

I'm new here but there seemed to be a ton of great information going around on this forum so I'm here to ask for expert help. I'm trying to reduce page load times for my site Adventographer.com and running into issues with 500+ http requests and random erratic TTFB's.

I host with Crocweb.com on lightspeed servers with SSD's (although shared) and attribute my erratic TTFB's (1-5 seconds) to the shared servers. but aside from that my load times are still high after trying all the optimizations i know.

It's a SSL wordpress site running Fast Velocity Minify and WP Super Cache, i've enabled Gzip and optimized images... I'm looking for some expert advice on how i can clean this up and make sure we see faster load times (aside from removing Adsense entirely)
