Week 4 LST & Hook Training for the SCROG Grow!


What’s up Cannabis Growers, and welcome back to Week 4 of the Screen of Green Series by GreenBox Grown.  My name is Dylan and in this video I will be covering part 2 of Week 4 which will will include all of the Low Stress & Hook Training I will be doing to these plants over the next 7 days.  I will also show you what the signs of nutrient burn look like and I will cover how to repair a broken branch.  As always, you can view the full Screen of Green Series at greenboxgrown.com under the videos tab. Alright, now lets get started with day 1 of the week.

It has only been a couple of days since I last adjusted the hooks, and already the branches have grown upwards a decent ways.  I’m going to adjust the hooks onto the new growth like usual, and you might be wondering.  If I keep doing that, wont I just have one long branch growing sideways.  And the answer is no.  The reason is when the branch starts to grow sideways, new branches will sprout out of it and grow upwards, so what ends up happening is you have a long trunk growing horizontally with a ton of branches growing out of it!  When adjusting the hook towards new growth, try to get it as close to the end of the branch as possible, as that will prevent the top from growing right back up too soon.  None of the new branches need hooks added to them, so that is all the training I will do for now.

This is the very next day, and already the branches have grown enough to have their hooks adjusted again.  It is important to stay on top of this training each and everyday for best results, but If you miss a couple of days here and there it will not harm your plants.  Ok, so this little branch here I was just trying to bend, snapped and almost completely tore off from the main branch.  

Luckily cannabis plants are extremely resilient and can easily recover from this kind of damage if the proper treatment is given.  All you need to do is take a piece of scotch tape and wrap it around the branch right where it snapped, so the tape is holding it back together with where it broke off.  Once you have it securely fastened you are all done.  Make sure there is no fan blowing right on it or any sort of breeze that will cause it to move around as that can prevent and slow healing.  But what will happen is the branch will fuse itself back together and the branch will continue to grow big and strong.  Here’s a quick shot up close with the tape attached.  You can see I got the fan leave stuck in there and thats ok as long as the branch is being held together.  

Another day later, and I will be adding some more hooks to these plants.  But first, I will adjust the ones that have already been added.  You can see these plants have pretty much all filled up their pots with tops and branches, which is exactly what we want.  With most of these plants I will now start to train them out over the edges of the pots, and with this one It still has a lot of soil to fill so I will cover that up first.  It’s important you train those branches that are in the middle and up high light these because you really want to expose the center of the canopy to as much light as possible for the best results!

Here’s another close up of the broken branch I am fixing with the tape, and you can see it is still perfectly healthy looking and still vibrant which is a good sign.  It will take a week to 2 weeks for it to completely refuse itself back together, so I will leave the tape alone for now.  

As I am looking through the plants, a lot of these tops look like they don’t need their hook adjust yet and can grow a little more first so I will just leave them be.  There are a couple that need slight adjustments or a little LST but that’s about it for now.

This is the final day of Week 4 and the plants have grown a decent amount since the previous day, so they are ready for some hook adjustments.  At this point however I will not be adding any new hooks as they are not needed to be at this time.   You can see this leaf here is browning and showing signs of a nutrient burn or other issue.  Some of the other leafs have some light discoloration around the edges which is a mild burn so nothing to really worry about.  I will just lighten the nutrients a little bit.  Also, if you have leaves closest to the fans that are yellowing or browning, it could be due to too much wind blowing too forcefully on them, so always consider that.

Alright folks, that is the end of this weeks Training as well as Week 4 for the Screen of Green Series by GreenBox Grown.  I will be back with Week 5 for the SCROG series shortly, but in the meantime you can visit greenboxgrown.com for the rest of this series.  If you enjoyed the video, please give it a thumbs up and comment below with your feedback.  Also don’t forget to subscribe to my channel and turn on the notifications for updates on my latest grows!  As always, thank you for watching and until next time…
