New northern lights grow

I’m doing an indoor grow dwc with northern lights. I’m at three weeks of growing. Should I start flowering? I topped three of the plans four days ago.


They’re big enough that you can start whenever. Your plant spacing is a little tight to be doing much topping/training in my opinion, but kind of late for that. Due to that, I probably wouldn’t wait too long before flipping them.


Tigh em out or surper prune

How much should I prune they are only 10inches tall right now.

No pruning!

Are you any time constraints? Generally they need 8 weeks of flowering. The longer you let them veg the bigger and more bud you will gt from them. If there is no rush let them grow!

I let my girls go for 6-8 weeks before flowering them!



I let my NL clone grow to 21" high before I went to flower, and it stopped around 44" high. No SCROG or any LST. This is just what the strain will do normally: A little over double in height. If your grow room is short, you might want to keep this in mind. But also you should know that vegging longer makes a bigger plant which improves yield. Some people grow NL TREES outside and get massive yields.


Is this a male or female?

You need to flag some experts like this:


Just a tad too early for me too tell, but I’m leaning towards girl. Unfortunately Your pic loses focus at the high site zoom. Here are a couple of pics that might help!

Show beter pic can’t see properly in that one :point_up:

One of the plants in the middle is not growing as well as the others. The leaves are dropping and not flourishing like the others. I want to take it out and let the other ones take up the space. My problem is the roots are attached to all the other roots I tried to take t out but I don’t want to pull to hard. What would happen if I just cut the roots off and left them in there. Would it destroy all my other plans and rot?

I think we need to see a picture @Vega1robert

White or natural light please!

It looks like a male to me but i might be wrong.

Its not male got hairs all over it

All the plants are starting to droop now. Some leaves are turning yellow. Not sure what to do?
