Overwatering? Possible nute tox / def?

From the pictures I cannot see too much N? The pictures do not show the whole plant.

From the pictures I cannot see too much N? The pictures do not show the whole plant.

If you check the pictures from earlier in the thread, this started from a bit of n tox. Clawing leaves and burned tips etc. Now, a few weeks later, the tips are still clawing and burning even more severely, but some of the other leaves are displaying chlorosis (general yellowing) while also having burnt tips. I still think there is too much N as if you look at the latest pics I posted, the colours of the plant are contrasted between either way too dark green, or too light green, although both of these sets of leaves have burnt tips and clawing. Apologies for not taking a pic of the whole plant in more recent pics, I just took pictures of the areas that display problems the best.

If I could try to describe how the plant looks as a whole, most leaves are clawed with minor tip burn, some leaves are yellowing severely as well as having burnt tips, some leaves tip burn has advanced into total leaf burn + death.

Overall, knowing what I've been looking at the past few weeks, the tip burn seems to be getting worse and killing a few leaves, some leaves are yellowing as well as having tip burn, and some leaves have met a very swift death from something that looks like K deficiency. So im stuck not knowing if the plant is hungry or still overfed by this point. It seems like a combination of both.

Do you know how to do a slurry test? Do you have an EC meter? Using a clean Stainless Steel spoon dig down into the root zone and retrieve a soil sample. In a clean glass mix one part soil two parts distilled water. Stir often for 15 minutes then let it sit for 15 minutes and read the EC. This will not tell us the balance but the overall nutrients available to the plant. This is invasive and I only recommend it when you just need more data to make a decision.

Your lighter colored leaves may be closer to the correct color but look light against the really dark green leaves? You know plants loose leaves as they age and even I cannot stop this on my own plants. The flowers still come out amazing.

Hi mate, I have a pH meter and an EC meter. pH of the slurry was 6.45 but the TDS of the slurry was indicating 125ppm. I was only able to take a shot glass amount of soil so I'm not sure how accurate this is, especially given that my tap water is around the same ppm (120-130). Also keep in mind the nutes are bottled organics and not salt based nutes.

Whatever the problem with her, she is now rapidly getting worse with chlorosis affecting newer leaves around bud sites and buds not developing at all. I didn't want it to get to this but it seems she might be a write off if she keeps getting worse at the speed she is. Not far enough into flower that I could limp over the line, looks more likely that she's going to die soon. and I'll have to cut my losses.

I've attached pics that hopefully better show the problems. They aren't critical yet clearly but the rate of worsening is worrying me.

I just fed her again today finally. 0.5ml grow 1.5ml bloom.

This confirms that the plants are hungry and not locked out do to over feeding. Feed that girl! Even organic soil should read ~300+ PPM

Got it! I just fed her today a few hours ago but fed her with the clearly deficient 0.5ml/1.5ml regimen... Should I wait until the next feed watering to feed a higher amount or would you recommend feeding the higher amount right now? I'm concerned with the amount of damage that could happen over the next week with no feed.

Do you have Recharge if so now would be a good time to use it. The plant appears to have plenty of Nitrogen but other elements are low so it is a tough call.

No recharge unfortunately, just grow, bloom and calmag. I would agree that the plant has plenty of N but I suppose I need to keep ratios correct, so my next feed should be 1ml grow / 3ml bloom?

Given I just fed her today the damage should slow down a bit, hopefully I can make it to the next feeding. Two plain waters coming up

Hey, one final question (assuming we've figured it out, fingers crossed), if the light feed I did yesterday is still insufficient by the time her next water is due (tomorrow or day after) and the damage is still advancing quickly, can I feed again (I'll be doing 1ml/3ml) before returning to the standard cycle: feed, water, water, feed, water, water?

Thanks once more for your help and patience.

Give it some more time to work.
