Your leaves look pretty drained of nutrients. Since you stopped adding nutrients to the water there will be a point where the plant will start to consume feed from other sources, like sugar leaves if it needs them.. so be careful with how long you run her.. white hairs and fattening up means two things; one calyxes are still forming and two it's still looking for pollen.. bud's will continue to swell as long as it's looking for pollen but at a certain point the nutrients it needs to produce will not be worth it since you're feeding just water. As well, cannabis tends to throw male flowers at the end of it's life if it hasn't been pollinated. I've noticed this especially in the ruderalis (autoflower) gene because the plant wants to procreate. Be on the look out for male flowers and sugar leaves deteriorating if you continue to run her! :thumbs:
