Hi all,

3 strains:
Left - GDP
Right - Bubba kush
Front - Green crack

Staring week 7 from flip.

The Bubba is not happy... same feeding

I am feeding with Advance nutritions bloom A+B, Sensizym and rarely adding calmag.
Usually every second watering, I gave her every last watering in the last 3 watering, no help.

PPM 1100
6.5 Ph tap water
No over watering
No heat

Medium is soil(peat with a little coco fibers) with a bit too much of perlite and vermiculate than usual, I added too much.
Not a very good buffer, but what can I do.. its the end of the grow now.

Only upper leaves turning yellow, old leaves are good for now, from what I read its a mobile nutrient deficiency?
One of the N,P,K?
Looking at photos, it looks like a Zync deficiency but its hard for me to tell...

Any identification?
And should I worry in this stage of flowering? I have 4-6 weeks left

Thanks

If that's Pre 98 Bubba Kush from clone I've found they don't like really intense light. Both of my runs with it have had some light stress issues.

Interesting, I have two 150w led boards.
The leds are 50 cm over the buds, but the right one over the BK is the UV led, the left one has no UV
Can it be a light stress??
She has issues since the grow phase..

Immobile nutrient deficiencies affect new growth. Zinc is an immobile nutrient

Yes you are right, I read the opposite here but its wrong.
So I have immobile nutrient issue, that's a start..

Any idea what deficiency?
Thanks

You're 7 weeks after flip. Are you sure the Bubba is a 10 week strain? What is the breeder? Ive grow Bubba and it only took max 8-9 weeks. It just looks like your plant is finishing off, no? Trying to fix deficiencies and or anything now would not be a good idea in my opinion. Just let it go and keep doing what you're doing. I would start cutting back on the nutes next feeding too.

If Im wrong please someone let me know but it looks like that plant is almost done maybe another week and a half,two weeks max on the bubba, doesnt it?

I Agree with what he said. I wouldnt try to fix this now if shes finishing off if you go trying to add a bunch of sups when its trying to finish off it might taint you're flowers.
Looks good to me

Do you feed with cal/mag every time?
Can also help with this fade.
Wont keep it away but it will just help keep it off a little longer till the end .

Yes you are probably right..
BTW its bubble kush, from Nirvana seeds, "Flowering time will vary from 56-63 days depending on phenotype."
From my experince with them, it will be minimum 70 days

I Would try to give it more of whatever you use for calmag then. I have to feed my girls every day not just water.

Do you have any pics of the deficiency when it started?
Looks like N deficiency to me.

Isn't N deficiency starts at old lower leaves?
Click to expand...
I agree that N starts from the lowest leaves in veg. I don't find that to be the case in late flower when a plant has been topped a number of times.
No pics of an earlier version of the deficiency? That's a shame. I would have liked seeing where exactly it started because it didn't start in the new growth.
I can say it's not calcium, Mg or iron. It's not PH. Don't know if it could be sulfur. The others are healthy with no Sulfur deficiency. Different strains have different N demands. I'll stick with thinking it's N for now.
Good Luck!

Drop the AN fertilizer for gh or jacks they leave stuff out/put in to few micros per type so you run into problems and buy another one of their products to add and fix it when it all could’ve just been one or two and maybe some Epsom salt.
