How many more weeks do I have until harvest

This is my first grow. There are northern lights started from seed May 3rd. I think I have two to four more weeks. When should I stop adding nutrition to the water? My run off ppm is 1350 and ph is 6.1

A few. Once the hairs get more brown, get a jeweler lens once the tric is about ready to harvest is around 80% milky 20% amber

This is the one I use.


I will get one and try to put up some pictures with it.

Does it matter if some of the pistils are still white ish ? I see a few amber trichomes on mine and a lot of cloudy and still a few clear, can’t get any decent pics though I’m still trying :joy: but a lot of the hairs on the main Kola are still whitish/ambering slightly

Pics or it didn’t happen

I am trying bare with me lol got to hold the loupe to the iPhone camera lol I’ll do my best

Stop nutrients 2 weeks before harvest. Do you give it nutrients every watering? What is your soil? She looks pretty well.

USB scope is the way to go. Northern lights photo from this morning. Just a few amber here and there, and still a lot of clear. Bidding my time.


Yeah I have ordered one of those all I have is a 60X jewellers loupe so it’s quite hard to take photos at the moment :laughing:

Sorry, could respond until now. I just joined and was limited to so many messages. Thanks everyone for all the advice. I did give them another dose, also trimmed up some fan leaves. I will start the flush again and hopefully soon I’ll get to harvest.
