Urgent advice - plants are too tall...what can i do

Got an issue with the height in the grow room ... i will quickly explain

tent - 1.2m wide, 2m tall
currently using MH for veg, temps+hum are pretty much spot on

8 plants

(1)
x1
Seeds from friend (sweet tooth or another)
Largest (roughly 60cm)
4th week in veg
Not sure if its male/female etc (still no signs)

(2)
x2
Seeds from friend (sweet tooth and/or another)
Both same height (roughly 50cm)
Again, not sure if its male/female etc (still no
signs)

(3)
x3
All three are roughly same height 15cm
Female cuttings, strawberry haze allegedly

(4)
x2
Chronic (purchased from serious seeds)
Both just starting veg, starting to show a few sets of the jagged type leaves

My questions is this;

All the plants that are under (1) + (2) are getting too tall...cant leave them any longer in veg...the strawberry haze (3) are looking good but the Chronic is so small...

Can we stunt the growth of the plants (1) + (2) to let the Chronic catchup? Or...do we put them all into flower (chronic too) and just hope for the best?

Im worrying that not only are (1) and (2) going to be big...but they havnt shown any sign of sex yet...if one or more are males...they would ruin our female cuttings.

Can I super crop (1) + (2) to stunt them growing upwards? What about triming opr pruning them? I havent done that either...

The stems are massive, i dont think i could bend them over...maybe bend them to the side (lst)

Is it too early for the chronic...to flower?

So many questions and so many problems!

Any suggestions or ideas would be great
 
Nice one guys, thanks for the advice...I found out just there that the are all female...well chuffed! :) :joint:

To say im a little nervous about what i have to do is an understatement.

I found a post on the RIU forum by kindprincess, which had the following;

this is from greg green's cannabis grow bible...

FIM Technique
There is a topping method known as the FIM technique. If you push the leaves apart at the very top of the plant you should see a small bud (not flowering bud but an actually leaf bud). Use a pair of nail clippers to pinch off about 3/4 of the bud. This should result in more than two top colas being developed. In a single FIM clipping you can produce up to eight new top colas.
The origins of this technique are humorous. As the story goes, FIM was discovered accidentally when a grower messed up a topping exercise. FIM stands for: "Fuck I Missed".

Super Cropping Technique
Another method of topping is called xSuper Cropping'. By taking a branch between your forefinger and thumb you can gently crush the branch, causing it to develop multiple branches above the crushed area. You must crush it on the correct side or risk breaking the branch. Just squeeze lightly until you feel the branch give, then let go. If it gives easily then you have crushed it on the correct side. If it is hard to crush and the branch splits then you have chosen the wrong side. Practice makes perfect with Super Cropping.

Super Cropping should be carried out during the second or third week of vegetative growth and does stunt the plant. You should also note that plants that are Super Cropped can remain in the vegetative growth stage for twice as long as normal but the end result is a very bushy plant with multiple node regions that should all produce bud. Many growers have thrown Super Cropped plants away because they believed that the plants were not flowering in time. If you Super Crop your plants make sure that you have the patience to wait until the process is finished which — usually about four to six more weeks of vegetative growth.

HOW TO MAKE CANNABIS BUSHES
Some people prefer their plants small and wide. Fortunately for them, making cannabis bushes is a simple process. During the third week of vegetative growth prune half the plant's branches. Cannabis plants need at least 50 percent of their leaves in order to continue growing without experiencing fatal stunting problems. If you prune off more than 50 percent of their leaves, you may end up killing your plants.* Do not prune only one side of the plant; prune both sides to achieve the 50 percent. You may also prune the main top cola if you want to split it into two or more parts.

If the prune cuts you previously made grow new branches and leaves, you may wait until the fourth or fifth week of vegetative growth and prune again, leaving 50 percent growth.

During the seventh week of vegetative growth you'll notice that your plant has started to grow outward more than upward. Let's say you have a plant with eight shoots. That means it is four nodes high. You prune the plant and end up with 16 shoots, but the plant is still only four nodes high. Now this does not mean that you can keep doubling shoots forever. Pruning merely pushes the plant to grow all of its shoots early. If you keep pruning a plant that is four nodes high until the eighth week of vegetative growth, the greatest number of shoots you will get will be about 32. Most [URL="https://www.rollitup.org"]marijuana[/URL] plants will not grow much beyond this factor, but again this is strain-dependent.

Now each new shoot has a junction point or a node that it grew from and each node should produce bud during the flowering stages. It is possible to create a [URL="https://www.rollitup.org"]marijuana[/URL] plant that droops over the sides, completely concealing its own pot. With the right strain, it is also possible to have a single plant spread over an entire 6x6 foot space using this method. Creating cannabis bushes usually requires a few additional weeks of vegetative growth.

Even tho im in the 4th week of veg (almost 5th) and stems are very thick, its ok to lst them? Just a little at a time...everyday?

Also, when topping you just cut off 3/4 of the top bud? By doing this, all the growth will be put into making the plant bushier? Does this mean I can leave them in veg for longer until the small chronic plants catchup?

Sorry for all the questions...i would hate for something to do wrong.

Thanks folks!!!
 
me again, does anybody have any good material/guides/videos on

topping
super cropping
lst

just so i cut/bend/top in the right places
 
topping you dont cut any of the actual bud.. you just cut the entire top of under the 2nd or 3rd node on the stem... that makes the plant think it doesnt have a top to it and makes the side branches grow upwards.. it stunts growth a little because there is a recoop time.. just so you know...

you can start to LST, but your plant is pretty much to big at this time to really benefit from it..

your best bet would be to supercrop or top... supercropping is easy and there are a lot of how to videos on youtube about it...
 
Hey simpsonsampson420,

$hit, i used the method in my 2nd post;

FIM TechniqueThere is a topping method known as the FIM technique. If you push the leaves apart at the very top of the plant you should see a small bud (not flowering bud but an actually leaf bud). Use a pair of nail clippers to pinch off about 3/4 of the bud. This should result in more than two top colas being developed. In a single FIM clipping you can produce up to eight new top colas.

You think i should cut it again - between the 2nd + 3rd node?

I cant find any good videos on topping/super cropping/fim.

i downloaded
Jorge Cervantes 1, 2, 3
Seemorebuds 1, 2, 3
Mr Green

Youtube
Cropping 101-110 (Ryan from Medical Marijuana Cultivation)

But they dont really give you good examples.

Can anybody point me in the right direction for the definitive tutorials/guides/how to's? I would prefer video's if poss.

About to switch to flowering...i would like to leave a few days of recovery...just in case.

Cheers again folks, sorry for all the questions
