Torrents not working at specific periods of the day

Has anyone faced this issue lately? I have A-OK line-stats and a 4mbps connection with zero disconnects etc. At specified hours of the day, like sometimes in 10-11am times and then in the evenings, the torrents won't go above 2/3 KB/s , as if they're being throttled. I'm using private trackers with very good Seeders/Leechers ratios and https downloads max my 400-500 KB/s bandwidth but the issue is with torrents only. When the torrents don't feel 'throttled' i get maximum bandwidth speeds on them.

Is PTCL limiting these as certain rush hours?
