I didn't document anything so it is certainly possible I could be off on the timing a little. I used granular fertilizer which may take longer to manifest issues than liquid - not really sure what you used, but if liquid that could account for timing differences , not to mention all the other possible variables that might come in to play. Let us know what you find out with your soil analysis.

Will do. I used a mix of organic dried blood 12-0-0 bone meat organic 3.5-18-0 and organic potash. To give a NPK plus I mix it together. Put a few spoons per plant, it was height dependent tho. I use liquid seaweed but that’s nothing really NPK wise more micronutrients. Yeah I looked it up liquid shows in 1-4 days and granular takes 2-3 weeks to show. Yeah other variables may of contributed.
Yeah I’ve applied waiting for RHS response

The rule of thumb that ive always heard is whatever symptoms you are seeing today is a result of something that happened 2 weeks ago.

I fertilised on the 4th July with all granular stuff... so that doesn’t add up. It can’t be fertiliser burn it’s been too soon, I’m confused now

The best way to get control of the fertilizer program is to calculate in grams how much N, P, and K is being allocated on a weekly or monthly basis and adjust the dosage based on how the plant reacts. A handful of this and a spoonful of that doesn't really mean anything.

Have you had a lot of rain lately? My Basjoo leaves were looking similar after several + inches of rain in Illinois. The plants finally broke at the base.

It’s in a raised bed in a polytunnel. So I add all water. I only water on hot days once a day in the morning giving a handsome amount eg 3-5 litres

sirdoofus

So the pics you fist showed were posted on the 5th and then another on the 8th, and you fertilized on the 4Th? You You also said ".....1-2 weeks, maybe even less..." transpired before you noticed anything...not busting your chops, just want to make sure I am understanding the timeline correctly.

If you took those pics 1-4 days after granular fert, you are right, it should be too soon. You didn't by any chance mix in old soil/medium that may have had fertilizer already in it did you? I do that sometimes when I am have more potting soil than I can use in a reasonable time frame. Or possibly less than completely composted chicken manure or something like that?

Yeah. That’s a tad confusing. Sorry my bad I’ll break it down.
So, I fertilised with my dried blood, bone Meal and potash all organic on the 4th in the afternoon. The dried blood was said to be fast acting. I can link it below to show the eBay page,
Bone meal- https://www.ebay.co.uk/itm/401925842...IAAOSwkXBeE193
Dried blood- https://www.ebay.co.uk/itm/401921465...IAAOSwCXVeFEBc
Potash- I got on Amazon. By miracle grow. It’s all organic.

Exactly a month before this, I used organic. 7-7-5 by miracle grow. It’s granular

However this month I wanted to change it so mixed the things above form eBay not including the 7-7-5 and put 1-2 handfuls by a plant and watered In.

The photos I uploaded from above are from that day/ 5th so they were there. So yeah, I don’t really understand it either now writing this all down. Cause it’s all granular fertilisers but the results showed wuicky and it’s all organic ...

Odd maybe it’s nutrients deficiency?
I
Hopes this better explains things. Even im confused to be honest. But I didn’t add more soil just mulches. I think. If I did then it wouldn’t of been enough to cause over fertilising. I did put down some chicken manure stuff. Not pellets it’s like a open bag down alos, but that was a tiny amount and I put it fown along with the others.

sirdoofus

Hm...I guess if you just leave them alone, other than water, for a few weeks you will likely get a better picture of what is going on. If they recover without intervention then maybe it was fertilizer. If they continue to display the issues you have noticed, then maybe a deficiency or some other problem not associated with over fertilization. Definitely keep us posted.

Yeah agreed good idea. I’ll update you what the next leaves look like! Which should be in a week or so. But it’s odd as some plants are fine other aren’t. All in the same area. I gave them all the exact same thing. Is weird lol
Thanks again for the help. One day I may undersrand this stuff��

OllieB497

So the new leaves still have some white on them. Not good, I have a theory though.
So a few months ago I pot potash down, this was beginning of spring,
Now I was naive to the fact it increases soil ph. Now it takes time to break it down, but over time it’s increases ph of the soil. I remember spreading it around more around some plants than others. these plants are being affected now. The Orinoco and namwah mainly. So the ph is higher meaning certain micronutrients eg iron aren’t as available.
Giving the nutrients deficiency look like the photos above. So maybe that could be it. The ph of the soil is too high. Some nutrients are avaiove and others aren’t.
It doesn’t help explain the leaves thag are strangling itself.

So what do you think? Getting my soil testing kit on Monday!

sirdoofus

Interesting idea. Let us know what you find out.

Another idea,
Boron deficiency?
Look at the screenshot below,
Thank you

I’ve done so much research todya on my day off. But I think I’ve come to a logical conclusion.
It’s NOT over fertilised. It’s the opposite. The photo above comes from a calcium deficiency. So if anything I have not enough micronutrients!
Boron, calcium abs a few others.
Have a look at the website below. But it’s not over fertilising. The symptoms are closer to deficiencies!
You have no idea how long I’ve been looking at this. Sorry I’m a tad overwhelmed bu it.
Link below to what I’m going off but I’ve crossed referenced it and others sites say the same.
