Early flowering plant yellowing heavily

This plant is in need for help as its rapidly losing all the foliage. Its in week 6 since flipping to 12-12 flowering cycle. Signs of yellowing appeared midway week 4 and within the next 10 days this happened and there are barely any leaves left.

Took advice from a few fellow members here saying to up the N nutrients as the plant is hungry, but it didnt change much. If anything, now there's browning on some of the leaves that are left.

So my questions are:
- Could this plant make it and finish flowering?
- Should I keep feeding it nitrogen nutes or stick to P, K only?
- What could be causing this?

The plant is in 7 gallon fabric pot, grown in organic soil with liquid nutrients under 600w HPS wtih steady 26/20 day/night temps.

Can we see a picture of your plant?
But it sounds like your asking for help too late, plants not going to recover 6 weeks in flower

And this is how it started 2 weeks ago (the bottom plant is the one from the pictures above). It just started losing color and within a day or two all the bottom fan leaves turned completely yellow and it continued progressing.

Yes the plant will finish flowering, the yellow leaves will not have a massive impact on the crop size

- Should I keep feeding it nitrogen nutes or stick to P, K only?

As you have lots of yellow leaves i would give the plants half strength veg nutes for the next 2 weeks
- What could be causing this?

The fan leaves turning yellow is caused by the plant not being able to uptake nitrogen, there a number of things that can cause this.

I agree with Markshomegrown;

- feed half strength Nitrogen nuts and have a look at what your CaMg feed is as it looks a little low to me from the blemishes on the leaves.
- I would also mix a straight water 5 liters of PH 6.0 and pour it through your medium and collect some run-off to check the PH and EC, you may have excess salt build-up in the medium causing nutrient lock-out.
- whatever your fix is going to be, do a 1/2 strength as mentioned above - you can always increase the nutrients but you can never recall them.

good luck and keep us updated.

Thanks for the response guys, I have been feeding it half strength veg nutes BioGrow from BioBizz at 1ml per 2L solution along with Algamic and BioBloom from Biobizz (calmag and P, K). I've used these nutes for the past 3 grows (all my grows lol) and I thought I had it dialed in.

I guess I could've been starving this plant as it's twice the size from all my past plants because of supercropping, and I was afraid to up the nutes that much, I just used the same ratios but with 25-50% more water than on the other plants.

I will try flushing it before the lights go on today, and feed it half strength veg nutes and full doses of bloom and calmag and will update you guys.

Also, on a prior post, someone mentioned that there are signs (on the pictures posted below) of the plant starting to hermie, so what do you think?
I may need to remove the plant from my grow room if thats the case... I haven't noticed any "bananas" its just these weird looking, dried calyxes with orange pistils within them (albeit I haven't had any experience with hermie or male plants to know for sure).

I appreciate your post cause I will glean some more tools. I had this same sorta thing happen this year outdoor (still learning). My issue was underfeeding and it responded once I fed her but you have been feeding yet have the same thing going on (yellowing in flower). Some of this is good so I’m told. I am trying to understand something you touched on here…i just don’t get how to calculate the “1/2 nute” thing when the size of the plant combined with the amount of water she drinks could be so drastically different from plant to plant <<or>> indoor vs outdoor. Next year I’m going to try 2 or 3 and do a few things different to each one but I’m def gonna follow along and see how you finish up! GL

Yeah, well I had read up on basically everything before starting my grows but 3rd time in, this is what got me good.
First time dealing with a plant this tall (and first sativa as well) so I didn't know how to feed her right. I guess I should've figured out that the indica which is half its size is doing fine with around 25-50% less nutrients, that I should probably up them for the sativas feeds to full strength.

Oh well, you grow and your learn. I'm just hoping that there arent any other major stressors at play with my plants as I would be gutted if I lose the indica plant next to it in case this has hermied and pollenated it in the process. Not sure for how much longer is it smart to keep them both in the same room.

As for your experience, I'd guess the already yellowed foliage didnt become green again but if the feeding made it stop yellowing, than that shouldn't have had that much of an affect unless huge portion of the foliage was lost. What's worrying in my case is that 10 days in after first starting to add N nutrients again, it's gotten worse, it didnt stall the yellowing, even some brown / dark patches on the leaves started appearing.

Scratch that actually, just spent an hour looking at every single cola and every bud to see if theres anything suspicious happening but there are no nanners 100%. Also its only been 2 weeks since these symptoms appeared so I'd guess thats not enough time for all that to happen.

Still wondering whether the plant will make it to finish flowering or it will need to be harvested early. Its not looking particularly good except that the buds are ripening fast.

This is the state that it is in right now, hardly any foliage left, and those that are still on it they look quite bad (pics bellow)

The plants starting to hermie, its not great but I have pull a few crops with 20-40 seeds, only worry when your plants are full of seeds, chopping early will give you weak bud, chopping at the right time could result in some free seeds, just have to work with what you have.

So basically seeds from a hermie would all be female, right?

Could it pollenate the plant in the same room and make it revert to producing seeds instead of ripening the flowers?

yes all seeds from a hermie tend be female,

yes, some parts of the plants will start producing seeds instead of ripening the flower, but there not much you can do about this.
It doesn't blast pollen around the room like a male plant does, you get a few cola's, half seeds and half bud, makes you jump when you smoke one.

At some stage you may have brought some good quality bud and found a seed or 2 in the bottom of the bag, same kind of thing.
