You are in the last phase. I am not familiar with the nutes or the plant, so I can't
really say what exactly you should do.
What I can say is to start taking off dead leaves. You don't want to pull leaves off, but when the get yellow and wrinkly,
they come off without effort. You want to throw them away, or compost them.
This is just a guess, go with your gut instinct, but I would stop feeding in a few days. Just water for a week or so.Then flush once
or twice and give it a couple days more. Then you leave it in the dark a couple days (optional). Then cut it and hang it to dry.
You need a loupe to see how the trikes are doing. Then you need to figure out at what stage you like trikes best.
Some like an early harvest, some like it late, some in the middle. I like it late, of course.
