Yellowing leaves at Day 42... HELP! (Dinafem Auto Blue Cheese/Critical+)

Hi

I was wondering if anyone could give me a little help...
I am growing Auto's for the first time and everything has been going really well, untill i get back from a few days away to find all the leaves are yellowing, now i know this is normal towards end of life cycle, but this seems a little early. (Dinafem Blue Cheese and Dinafem Critical+)

I have been feeding them with diluted doses of
20ml Canna Flores
10ml Rhizotonic
10ml Cannazym
10ml CannaBoost
5ml Canna PK13/14

All nutes per 10Ltr bucket, hand watered in Canna Terra Soil in 6ltr Airpots, flowering under 600 HPS

As you can see the yellowing is spreading and on some of the plants the yellowing is alot worse, new leaves turning yellow from start of their growth.

Any help on what can be done would be very much appreciated.



Thank you.

Are you maintaining your ph right?

Ive been keeping my PH between 6.2 and 6.5 and the run off is about 5.8

I had similar issues switching from veg nutes to flowering nutes too soon. If you switched as soon as flowering started i would recommend sticking with veg nutes another two weeks or so in the future or deal with a nitrogen deficiency.

.

Flower nutes too early id say too.

Just add nitrogen problem solved pH is fine you can keep feeding like you are just add a lil nitrogen you'll be good

Long ago when I used bottled nutes I had those problems.
Now I'm all organic + never have the early yellow.

All you need for nutrients is BAS craft blend nutrient pack(top-dress/re-ammend soil), Worm castings, fish hydrolysate/black-strap molasses, and myco(basic compost tea).

Never had that problem since...I use foxfarm cocoloco for base soil, but any organic soil will do.

Thanks for all the replies

Wasnt sure about nutes with auto's to start, was advised not to give any veg nutes, so i went down a very diluted road, just cannazym, rhizotonic and a little canna vega, only started adding flower nutes once flowers about week 4 then i gave the dose mentioned, have added a little veg nutes with the flower nutes to add a little more nitrogen back and will be getting some mono nitrogen when the hydro shop opens up tomorrow, hopefully get some colour back in my ladies

Thanks for the help chaps

Yeah, I'm in same situation. Rapid yellowing of leaves on my Mk Ultra Kush. Doing the same as you right now, little touch of veg nutes until I can get to the hydro store. Fucking bank holidays...

Fucking Auto's more like lol... hope yours arent looking as bad as mine, but good look with the remedy

I'll take photos for you tonight. I'm at work, and have photos on my phone but don't show the yellowing too well. I think it looks fucking drastic, proper shame. Fingers crossed for us my bud brother!

@420Haze you run canna? Are you in Coco? I can give you a schedule to run

That's what I'm thinkin...

I'm about to start a coco hempy grow, and I'll be getting Canna Coco nutes to see me through, so I'd appreciate that schedule dude

I do run canna but im using canna terra, which is the soil one, but a schedule would be amazing and then when nutes run out if i still havent got the soil on lockdown i could change it up a bit, or at least try and work it out for soil nutes from yours

I use tupur it's like wild organic oregon soil/coco/perlite and this system pulls 2-3lbs a light on average and only human error is the actual act of watering

Check out my grow so you don't think I'm all talk on the FL og I grew I got 2lbs a light no c02 I pulled through whole room 1.2lbs a light but had lower yielding strains like Larry og and bubba Kush

Your setup looks sweet man, wish i had the space for something like that, and 4k lighting, i have 600W super lumen, a little off what you got going on, but its all about the grow man

If you have that schedule for canna coco can you throw a link up mate, to change id only need coco and get the A & B nutes, not much of a change and would appreciate as much help on feeding as i can get

A few photos, as promised.
