Stunted growth during flowering

konall012 · Jul 30, 2015

So I planted three Royal Bluematics in an indoor six weeks ago, and they've been going great so far. However, one of the girls is seriously stunted, she's at about 12 inches (the other two are at about 15 and 17 inches). She's hardly grown at all in the last two weeks (the other two went from about 12.5 to 15 and from 11 to 17 respectively), she's stuck at 12 inches. Also, the colour of the leafs is slightly darker than the other two, don't know if this is relevant? The buds look great on her, but I'm worried she won't grow any more. I've got about 3-4 weeks to go. I'm watering every 24 to 36 hrs, and a couple of days ago I switched from a 18-6 light regime to a 24-0.

I've attached some pics. Am I worrying over nothing? Is there a problem with her? Help pls!

Dang dude... that's horrible man, I'm sorry.... anywho, what size pots you got there? I had that same thing happen to me before, turned out to be root bound. Check the bottom of the pots. If your roots are showing I would transplant. But you said you where already in flower so idk. I would charge this one to the game and start fresh after harvest with the new knowledge you've gained from this grow. Idk if it's root bound I'm just guessing. That's really all we can do with the info that was provided. They look pretty damn healthy. This is my plant... I planted it June 1st and I just flipped the lights... check out the size difference. Granted it's in hydro but still, That was about a week ago. There was definitely something wrong there. Is it sativa or indica?

Regarding the leafs, if it's the same strain and one has darker leafs it could be too much N. But don't feed it N now it's too late. Also in flower the leafs start turning yellow and eventually fall off.

hmm, where did you get the seeds? You may want to try watering with ice water one time to try and shock the plant into new growth. close up pics on leaves would be helpful and if u tell us what the npk rating is on your nutes that will help too I respect the rootbound theory however those pots are kinda big so I don't think that is the case in this scenario. a tip for soil growers is you mix the food for all 3 plants in the same container (if it is same strain) that way all plants get the same nutrition. what is the temp and humidity in your room?

kenobi · Jul 30, 2015

Hmm... they indeed look rather large, but are they deep enough ? Ideally what temp should be 68° anything warmer Than that deprives the roots of oxygen so I agree with azarule, however it does seem like it's too late for all this... you're buds have formed and if I'm not mistaken cannabis stops growing once in flower. I believe it has a few inches of stretch but that's about it. It looks like good bud tho lol smoke that shit

Oh I forgot to mention as with any hybrid you run the chance of getting different phenotypes though it is rare in some plants it can happen to any hybrid

AzaruleGreen · Jul 30, 2015

You also could always reveg but I mean its a huge waste of time and money especially because your plant doesn't look unhealthy. The buds look nice too. If I was in your position I would label your plants as 1, 2, and 3 and take a clone from each plant. then when you harvest you can try and see if they have different feels to them or if one is stronger than another. Your plant isn't showing any signs for nute burn though you may be watering it to much that is possible because the leaves will droop like that when u over water and I noticed the second smallest plant droops a little too

crap how did I miss this when reading your post!!!!!!!!!!!!!! when flowering you need to 12 on 12 off. You can't give it 24 hours of light during flowering you will cause it to reveg. 18 and 6 was to much light too.

But it's an auto, everywhere I read it says the best light regime for autos is 20-4 or 24-0 :c

What was your light set up? I really don't know what to say... that's some crazy stuff. There was definitely a problem with the operation

Just a simple old 400w HPS, I switched from a metal-halide one about one or two weeks into flowering.
