early flowering, is there any thc present?

say a couple plants are chopped early, they have plenty of hairs but no visible crystals yet only flowered a couple maybe three weeks is it even worth saving or trash?

Id have a go at making hash with it, thats about it imo.

You probably won't get more than a paranoid short high.
Hash or oil is your best option but even that might be futile.

Harvesting time is crucial for outcome.
