ellowing has occuredI have 3 weeks left on them

I do Believe they are just using up the nutes from the leaves (often using up the nitrogen) and when all that can be taken is taken they die off. Awesome plants btw impressive for a 6x4x6 Box.

I'd say it's a mild copper/sluphur deficiency. That molasses will really be useful.
If it's not that, then it acually could be starting to die out. By the way your buds look, do you think they need more then 2 more weeks?

they have been on for 5 weeks today doc why do you think there is more than 3 weeks left ?

If the plant has a fast metabolism and would like to finish flowering earlier, the yellowing and withering are normal.
Usually in the last 1-2 weeks, plants tend to give all they have to finish flowering, so maybe that's your case.
I was asking if the buds look more developed then they usually look at 5 weeks, in order to establish if your plant is just flowering very very fast or really has a deficiency that can be fixed.

If it's just flowering fast, I'd like to know what strain it is.

its mango crossed with ak47 a friend had mango seeds and put male ak 47 plants in smae room as mango in flower and these were the seeds off them if i gry some bud pics will you have a look and see coz the hairs are turnig lovely and golden

well, you kno the bud is close to finishing when the hairs start turnin red/copper/brown.

A bud pic would be helpful to establish the state your plant is in.

dont worry this is normal your plants are using up the last bit of nutrients most likely the nitrogen

sorry had to go to mates to get pics what do you think that there might be less than 3 weeks its been 5 today ty

Jus hadd a bowl o' bong... cant really explain...https://www.rollitup.org/newbie-central/94073-how-start-thread-post-pics.html...this should come in handy

there on now

Still spacy, but I can definetly say that you have about 1 1/2 - 2 weeks more to go and still alot of green in those plants. So everything is ok, there's absolutely no need to worry.

thanks doc

Always a pleasure to help a fellow grower.

May i recommend you give it some molasses to it's final waterings (1tbs/1gallon). It will increase your terpene production and get your buds smellin crazy sweet.

Good luck and keep us posted!

Granted I am a new grower but from everything I have seen, read and heard what you are experiencing is normal.

If I understand you correctly you are in week 5 of flowering. If that is correct than your plant is using up the nutes from your fan leaves. This is suppose to happen.

Do you have a method of checking your trichomes? A simple hand held scope will do it for you. You will be looking to see if the trichomes are clear cloudy or amber. Mine are still mostly clear at 3 1/2 weeks with a few cloudy. Cloudy with mostly amber is what is desired for most people

they are clear mate standing up with a ball of glue on the end millions of them

and thanx doc keep you posted
