Is it ready to harvest

I'd say another week, probably minimum.

I think she hasn’t been offered the ideal environment to give me heavy buds. It’s a very ghetto grow, basically just light mix soil and water, with a single 18W led bulb. It was just a try for fun but as I said I’m kinda happy with what she looks like. Thanks for your answers, I’ll give it one more week and check on trichomes daily :)

Yo personalmente esperaría a los tricomas ámbar-marron, es más en la última semana de floración la mejora en los cogollos se multiplica sorprendentemente, puedes explorarlo tu mismo

Your buds don't look very dense yet and there is no amber trichomes, I would say you're close but not there yet. I would ask yourself did you feed many nutrients and did she have enough light intensity this round? Something to think about for next time. I say these as usually the buds should be alot fatter at this stage, they look quite light and fluffy, this is usually because of lack of light and nutrients. 🌱👍

I don't like to call it without a good clear look at the trichomes, but I would give it a couple more weeks.
