Hi everyone ! I'm new to the forum. I read it here time to time but it is the first time i signed up and post a thread. Because my plant is sick as you guess...
I had to leave the city aprrox 3 weeks ago for 10 days or so. And left my plant to my brother with instructions. When i came back to home i found my plant not in a good condition. I thought that it was nutrient burn. Because my brother told me that he followed the watering and feeding schedule as i instructed. So i had no reason to think that it was phosporus or potassium deficiency although it looked like a deficiency. Anyway, so i decided to flush and water her just plainly for a week. But my girl didnt stop getting worse. So i need your help. English is not my native language so excuse me for my mistakes. And thank you in advance for your helps.

1)Pictures are below with explanations.
2)Outdoor growing.
3)Watering Schedule (Regular after flowering) : Sunday( With fertilizers N-P-K ratio is 2-6-8) - Wednesday (no fertilizer) - Sunday(With fertilizers again)
Watering Schedule after this problem : Sunday(flushed) - Wednesday ( watered with no fertilizer)- tomorrow(not decided yet)

4)Soil (PH: 5.5-7.0)
5)Stage : Around mid flowering i guess.(17. or 18.week)


So the pic below is how i found my plant when i was back. This is 7 days ago.

All pictures below belongs today. After flushing and giving just water for a week. As you see it got worse.

I’m not positive but it could be a nitrogen deficiency. In late flower my plants leaves have looked like that but it seems a bit early

I'm thinking the same thing you did initially...a potassium deficiency. Many strains use a lot of potassium during flower. I have been using blackstrap molasses and it seems to work great, but my plants are indoors, and you may have to worry about bugs. Your English is very good by the way!! Have you been giving them any cal/mag, or do you think is there enough in your water?

I usually use 2-6-8 fertilizer. But I might try 4-6-8 . I think it won't do any harm, even it doesnt work. Thanks for advice.

Yeah bugs and birds gave me enough trouble. But i got rid of them somehow. If i use blackstrap molasses, all bugs in my city will come to my plant i guess :) No, i havent given her any cal/mag. As you said , i think there is enough in my water and media. But i can give it a try .Because there aren't many option left for me.
Also , that pot is bigger than it looks. It should be around 20 gallons. But maybe it is still small for her anyway .haha.
Thanks for your help and good wishes.I hope i can save her .

you have a few things going on here, pot size, and a few deficiencys, your plant is sucking up whatever you are feeding her fast, next time try to use a larger pot/container. Even trashcans can work, (new circle ones, you would have to drill holes. theres many diff containers out there that can save you a few bucks compared to what actual planting containers can cost. Keep up the work, we all learn! Peace!

This is good stuff too...and won't attract bugs. If you use it, you must add it first, and then other nutes after...and it will spike your ph. It's part of my IPM.

So we are not sure that if it is a deficiency or nute burn. Maybe both.

Hahah. Yeah i cant argue with that. It is actually 2/3 tho :p Should i add soil? Would it be any good at this stage?

Apparently the pot is bigger than it looks...10 gallons of soil should be plenty. Although it wouldn't hurt to top dress them a little

I would cut out the nutes for a while and just use water for a week or 2 and try to add some magnesium and potassium. It gets tricky because there are probably a few things going on. Maybe start with just water for 7-10 days and see how they respond.
