Late flower deficiency


Recommended Posts

Hi guys, i seem to have a strain that loves to rip out nitrogen in late flower say around week 7. I really want to push these girls to 10 weeks but i think they wont last.

Has anyone else had this experience with a strain? Im curious to see if there's something i can do for my next round.

 

Ive added a nitrogen additive at week 7 at 0.5 ml per L.  I think ill double that.

 

Any ideas, solutions?

 

Thanks

In my experience , cannabis does this normally, during the flower cycle, it stops using available N in the soil and starts to use the stored energy in the leaves as food to grow buds, i believe adding N at this stage could cause problems like over nitrification of the medium and lead to lock out of other essential nutrients.. 

 

Im no expert.. Lou knows her stuff.. a bit more info can only help..

 

Good luck with it all ,

From the photo... the leaves don't look that problematic to me... mind you a little more detail about what you are actually feeding the plants might help.

Hi Lou,

They have been fed vitalink a+b flower EC 1.5 PH 6.3 in coco.

And Canna pk 13-14 for week 5

In end of week 7 start of week 8.

regenaroot and backtakil for 1ml per L and 0.5ml per L (as always)

Some Silica and thats it. Pretty simple stuff

 

Im thinking that as sirvapealot mentioned, this is normal for this strain in particular.

 

Thanks

P.H. is TOO high should be 5.8.

 

They look a lot like Auto's are they?

In fact they look identical to my AK47 X NYLD F1

If they are, then that's pretty normal & they have come to the end of there life.

 

Nice tasty looking weed so tell us what is it?

Hi Buzzo,

 

I start them on 5.8 and increase later in flower to max 6.3,

 

Its a strain call mumba apparently. They are not an autoflower. They can push to 10 weeks mold dependent as they are very dense and heavy.

The only strain close to "Mumba" I can find is Mamba Negra by Blimburn Seeds, is that what you have? If so, the ec of your A+B mixture seems a little low. If you are growing this strain again, or another indica dominant variety, you might want to try them at a higher ec towards the end of veg and the first half of flowering (around the 2.0 mark).
