Turning leaves to hash?

My plants have been growing now for nearly 3-4weeks and i was just wondering if it is possible to prune the leaves and turn them into Hashis at the stage they are at now. I always thought that they do not produuce THC untill they start budding but im not 100% sure.

Ive left a picture of where my plants s at now.

Thank for any replies

brick top is right ur plants need the fan leaves to complete photosynthesis, and no u cant make them into hash, hash is made of thc which your plant has none of until the 3rd week of flowering but even then your not suppose to do more than a leaf or two of pruning in the flowering stage as your plants will use them in the last weeks of flowering for extra nutrient.

There aren't even any trichomes dude, it would be impossible to get any hash from those.
