Light confsuion URGENT!!

[canni13is]

lol we have got her so confused its not even funny.

Right now your lights should be 18/6 or 24/0 for vegging. Either one is fine but stick to one through the vegging stage. Once the plants are big enough and mature enough ( usually 12-15 inches tall) you then turn the lights to a 12/12 cycle. This forces the plant to start flowering ( making buds). You keep it on 12/12 all the way to harvest.

lol it is kinda confusing but it's ok because im getting good advice still. My problem now is that I want to sex them now because I don't have a big grow space and I have 5 plants in there now and I need to start doing some eliminating lol. will 18/6 cause them to show sex within a week or so? They all have 5-6 nodes on them. my tallest one is about 9 1/2 inches tall. they will be 4 weeks old on Sunday Feb 28th.
Another question I have is there a few leaves that are starting to curl or turn yellow on the tips. I am assuming this is a potasium deficiancy but not certain. Would it hurt the plant if I trimmed the tips of the leaves where they are turning color or curling. Thanks again.

[canni13is]

I never trim or cut off parts of a plant inless im pruning it for light reasons. Cutting these areas off are not helping the plant, its hurting it more then anything. If you just leave them be its not like its going to spread. If you have a nute problem you have to solve it by either stop feeding it too much or start feeding it more. For your first grow you are going to have some trial and error moments. Thats just part of the hobby. Your plants arnt going to die from a few yellow or dead leaves.

IF you must sex the plant right now.... you have to turn the lights to 12/12. AS SOON as the plant shows the sex switch back to 24/0 asap. This however will cause the plant stress and could (doubtful) but could push it into a hermie case. People have been doing it like this forever and and most cases works fine.

I guess many people don't realize this but a plant will PRE FLOWER on a vegetative NORMAL cycle like 18/6. The plant will grow a few flowers but not actually progress with the hormones to continue flowering.. that is, until you switch to 12/12. Thus, you CAN determine the sex of a plant by vegetative growth pattern over time.
Females will be slow and steady with even node spacing.
Males will grow taller and more robust with more spacing between nodes and WILL preflower a full two weeks before a female plant of the same age.

I'm not sure what is so confusing about it. Light cycle is one of those things you don't want to mess with, so stick to what is tried , tested and true.

Question:
Where in the world do you get 24 hours of light a day and see fruiting and flowering plants grow?

Answer:
Nowhere.

Conclusion:
Don't use 24 hours of light as a vegetative cycle.

Reasoning:
The plant will stay in a vegetative state with more than 14 hours of light a day. The only reason to use 24 hours of light is when germinating seeds out of a medium. With the light always on there will be a source for the plant to grow towards once it actually breaks through the medium. Once you have all your seedlings sprouted and growing resume a light cycle that contains at least 4-6 hours of dark daily.
When the plant is not absorbing energy and no chlorophyll is being processed the plant will generate more roots, this is fact.

Any of this make sense now?

:thumbsup:

Ok i should've been more specific.

Cannabis does not grow naturally where there is 24 hours of light a day. Isn't the idea behind an indoor Cannabis garden to provide the ideal conditions for that particular plant?

Weather & climate | alaska.com

Answer: seems Alaska could be used for a correct answer...... instead of NO WHERE.


And im sure people do grow cannabis there "naturally" and not just indoor as it is a medical MJ state.

18/6 , 24/0, 19/5, 23/1 i dont think you will see much of a difference to be honest. The most important thing is that the plant is noticeably getting alot longer days then it is nights to keep it in veg. state.

[moody420]

Oh, the argument about 24/0 vs. 18/6.....which is better? Honestly there probably isn't much difference....some people swear by one and some swear by the other.

I've personally tried both and I stick with 24/0. I do it because the logic of it makes sense to ME....maybe not others. 24 hours of growing is better than 18 hours and I like to veg my plants quickly to get to the flowering! I usually only veg for about 2-3 weeks...top them and bud them out. Some people say it's unecessary and a waste of electricity but I haven't noticed much difference.

so like I said, play with a few ideas and find out what works best for you with the type of strain you like to grow. have fun with it! it's ganja....it's great! :jointsmile:

[BobBong]

Agree'd to each his own, opinions are like arse holes. Everyone has one and they all stink.

I'm an 18/6'r and always will be!

Happy growing either way,
Bob. :thumbsup::rastasmoke:imp::rasta::hippy:

Actually my husband copied and pasted the thread I did and made one of the same because I spelled confusion wrong lmao. He is precise. But I don't see the big deal about having 2 of the same threads. You know you have a crap life if you have time to notice 2 of the same threads and still have the time and ignorance to comment on the fact. Weird. But anyway, I want to thank those of you who did give me some good advice. I have made a final decision, I am keeping the lights on 12/12 till sex shows, then I am putting it on 18/6 Thanks again everyone!
