Das Experiment

Plant is looking very healthy and huge has over doubled since veg, I've decreased the nutes this week as I'm getting ready to flush and harvest, I think in the next 10 days max, plenty of Trichomes and pistils with some turning amber and buds forming fast and getting fat, it's my first plant so not sure when to harvest, last week lots of Trichomes but not everywhere, this week Trichomes are everywhere even where in areas with bad lighting, I'm worried about missing the harvest window, the plant is still taking in a usual amount of steady pH water of 5.8 and is thirsty still and still getting fatter bud sites but some of the leaves around of the bud are curling a bit, any advice be appreciated as to harvest time etc
