Yes, I have the same problem - Which is why I made that note at near the beginning of the post about having to increase my server specs. This really makes sense as my Dev Server was only running 2GB and I had already bolted on things like Redis and Elasticsearch.
Bare in mind, your .htaccess file only controls the directory environment (e.g. anything running in the Magento folder).
Elasticsearch will be tapping into your system variables (not your Magento directory variables). Therefore, try increasing your memory_limit to 3-4GB in your main php.ini file. Don’t forget to to restart apache when changing php.ini.
