When are these ready?

For soil your PH is far too low Soil ph should be 6.3-6.7..yes you can get away wit organic nutrients ph doesn't really matter But if you adding q buffer it should be in a more desirable ph for soil. Also you're in fattening coming into Ripening. You need more PK. Ppm between 4-600 1-2 feeds every 5-7 days. Or higher ppm feeds with water follow ups. Also ur ppm is far too low. And your plant is feeding on itself massively. Its a bit late now mate. But you can still add Nutrients. Your still a bit off from harvest
