Even with a clear picture the chance of anyone guessing what your plants are is about as close to zero as could be mathematically calculated. I know of over 2,300 different strains and there are many more, and that wouldn't even take into consideration all the intentional and accidental mutts that have been created by individuals over the many years people have grown cannabis. Added all together there are thousand and thousands of strains to pick from and no one, and I do mean no one, can look at pictures, or even look at plants in person, and be able to accurately tell you what strain a plant is. Anyone who tells you otherwise is wrong.
