When to top

[Bigpapa]

Merry Christmas GWE!

I'm 3 weeks into my first grow. I'm growing in a stealth box that is 4' tall and has 1 Mars Hydro 300 watt LED light. I'm doing DWC using General Hydroponics 3 part nutrient system at the strength recommended here. My average daytime temp is 75-80 degrees with a RH of 40-70%. The PH of my water/nutrient mixture is typically just over 6.1. My plants look great to me but they aren't really growing tall. I'm wondering when to top them. I'm going to do LST in an effort to maximize my limited space. This first time I have 2 Northern Lights going. Next time I will only do 1 plant. Please take a look at the pics below and let me know what you think. Please remember that my main question is when to top and perhaps if you think that they look normal for 3 weeks of growth.

Happy Holidays from a rookie 😬

They look great for being 3 weeks old. I would say that you could right now cut off the top node of growth. One shows some nute burn, but only on lower leaves, not new growth, so not a problem there. I am not a DWC grower, but I am wondering if you should have spaced them further apart in your container, instead of side by side. It would give the roots and plants more room to spread out.

Yea. That's why my next grow will only be 1 plant. But for now, I want them in the center of the box so I can utilize the surrounding hooks for LST. I think I'm going to jump in and top my girls.

Thanks for your input.

[Bigpapa]

Well...........what's done is done. I topped my girls. I'm keeping my fingers crossed 🤞.

I'll keep my fingers crossed with you. Show new picks in a few days.

Yeah, they looked ready for their first topping. They look great at 3 weeks old!

[Bigpapa]

Ok. Here you go. Before and after

I also use DWC and and just starting week 4 of veg... I topped most of mine right around week 3 and they were just about as tall as yours maybe lil taller... I topped and then fim'ed the sprouts from the topping.. some of mine have a lot of under growth that I topped and fim'ed also.. I have a journal on this forum called "1st DWC grow journal" check It out... the pics are of my veg tent week 4 day 2 except one on far right is 10 days behind others

Hi Bigpapa

It's best to have 6 nodes on the baby before topping to the third node, if the plant is slow it could be weeks old before you see the 6 nodes not a good idea to use time on that question.

[Bigpapa]

Well.... they've been topped. Let's see how they do.

[wallnut]

[Bigpapa]

Ok. I will post updates and pics on this thread.

Also topped mine at 4th node (16 days), and am happy so far with the developing 8 colas. Pics are on my Bubba 2 thread: http://forum.growweedeasy.com/forum/...-2-we-love-you! Keep us posted, and good luck and best wishes for a fruitful new year with your new hobby! 🌿
