When to harvest?

My plants are about about 42 days into flowering. These 2 plants have some auburn hairs. Probably around 20 percent. How long before I should harvest? And will the buds fatten up more? The first 3 pictures is the bigger plant and that is aurora indica. And the last picture is a cross breed between blue mystic and aurora indica.

A few more weeks. I've grown aurora indica, and it was very tall too. In the future, you should consider pruning the lower branches before they get a chance to stretch. I'd leave them now though as there's no point to pruning this far in..

It looks good. I'd cut down on N a bit as it looks a bit glossy, but other than that, it looks healthy.

Yeah I transplanted a month and a half ago and flushed it a ton of times and haven't fed it any n nutes but it's still like that. I was thinking about 3 weeks. I would say these 3 have about a month or more? These lower branches grew too tall.

There all about 40 days into flower
