Week 4 into flowering How come some plants havnt grown in height

Ok im in week 4 of flowering and I noticed some of the plants havent grew at all in the last few weeks. Does anybody know why this would happen? Theirs 3 different strains in the setup but some of the ones that are the same strain have a big difference in hegiht. I heard that they might need to be moved around or something.

Im using a ebb and flow drip hydro setup I think thats what it would fall under. Using a 9 gallon tank with airstones and waterpump. And it drips on top 2 times a day for 5 mintues. Pumping CO2 also.

What shoudl I do on my next grow so this won't happen and all the plants will grow at around the same height?

thanxs for any help.

Maybe you have different phenos of the same strain?


Were they grown from clone or seed? Sorry if i missed this in your post

So they stopped growing up and are still filling out? That would be normal if that is the case, stretch might be over for those plants. If not then there is more devilish things a muck! I would recommend filing out a plant problem info sheet and post it for more accurate help on here...:jointsmile:

The stretch is usually the first two weeks, then the magic happens! I wouldn't worry about it. :thumbsup:

let me take a guess here ...... are the shorter ones on the opposite side of the light socket by chance?? meaning plants are farthest away from light socket.

No actually their not.......that would make sense if that were the case....some are directly under the light..

I heard someone say in a post on here don't use ebb and flow tray because the plants need movement just from their experience.....I never asked for more details but can anybody explain that more.....

An oh yea I started from clones.....maybe thats a reason....
The buds look like their still growing the plant stoped growing height wise..

Even if you grow from clones there is always runts. They didn't root at the same times even coming off the same mother. Maybe a smaller branch when cut. Most times if vegged long enough they will eqaul out. I can't wait for a 1 footer to catch up to a 2 footer.

The solution is to have more than twice the clones you need and then take a bunch that are all the same size and roots.

The bright side is they all smoke just as good as the bigger ones.
By the way they look real good.
