How much time before flushing and harvesting?

You shouldnt flush at all really. Read the studies, people prefer the taste of unflushed bud and flushing doesnt change the quality (unless you flush too early, then flushing can ruin their potential). Flushing is only good if you're trying to save on nutes. Once your trichomes start really turning amber, they will do so at a rate of about 5% per week. Having 20% amber is generally considered a sweet spot, so judging by that, I would say you have 3-5 weeks to go. If you can, put them under a higher magnification, under 60x, I bet you'll see a few ambers.

Hi, You still have quite a bit to go. A few signs Before harvest can be, yellowing of lower leaves, red pistils, Thricomes start to turn amber. When flushing stop nutes and just give the plants straight ph’ed water for a few weeks . Some of the leaves will turn yellow but it is normal the plants will be using the nutrients from fan leaves to generate greater bud sites. Just dont let the entire plant turn yellowz. Once you are 50-60% amber thricomes and most of the pistils are red and curled up, you can harvest. Some people leave the plant for longer periods for a more sedative state. Up to you meow Happy harvest!!!!!!

That's a GREAT mystery don't know the strain. Looking at the pics start flushing in 2 weeks.👍👍 From The White House
