Any ideas what this could be?

Great idea to rinse/flush prior to planting. That's why I like this forum so much!

Same here most of the time..then you can check pH out as well. I give more time to fry out the post..maybe 5 days but I'm rinsing/pHing 5 gal smart pots.

Sorry about the wild goose chess, got thrips on the brain!

No wild goose chase at all! Will diffently be keeping an eye out for the bastards!!! A lot of folks here have complained about them!!! I have a couple of grows under my belt and don't keep as close an eye on them like my first grow, checking them four and five times a day!!! 😀
