is it nute burn?what should i do
Research! Bloom nutes need to be a little lower in N and a lot higher in P than what you have. I am also a noob, but looking like you got some serious issues, possibly N tox, but definitely P deficiency if you are using that and 8 weeks in. Good news is it will all be over soon and you can learn from this expreience and get better with your next. As to how to fix, not really sure what to tell you at 8 weaks except flush and pray. Lol

Well my drop hits 5-15-14 + 0-52-34 + 0-0-1 +5-1-1 in flower...

What pH you dropping at?

12-12-30 some sheet is odd, would need feeding schedule modifications. Like every 3 water feed..

(Paused)

Medium?

pH of the solution?

Drainage in medium not good?

Ever work on the root zone?

That 12-x-x is antagonising the problem and shrinking your yield. You can use it but gotta be on top of it.

You were/are flushing in the bud stacking phase.

the drainage is normal everytime there is like 20 to 30% run off
:-" donno the pH tho my medium is soil+some homemade composts
yeah i flushed like a week ago tho it resulted in potassium deficiency

You're not adjusting pH of nutes?

That soil no pH sheet only works with microbiology in the rhizosphere.

Soil looks compacted as well, needs a bag of perlite. When you water does it pool on the top or drain through immediately? Does it stay moist all week after water?

Don't think the flush did this.

Soil feed would be maybe once a week. Or every third watering.

it pools on the top for some 5 seconds then its gone in the soil
i sure have overfed it how can i fix that given that im in my last weeks of flowering?
should i get the run offs pH tho to get a glimpse of my root zone pH?:-?
is it fixable at all or is my plant as good as gone?

Well, they have more than a week, due to issues. Fixing it this late.?. Honestly idk about that. Just feed lightly maybe once every 7-10 days.

It's containment/damage control at this point.

I would start focusing on the next round to avoid this issue again.

Side Note:
Idc what anybody says about soil, pH nutes until you understand what's going on under the hood and have a grasp of CEC. Saves some issues for newbies.

Honestly, I think the Soil, EC, pH is suspect in this.

We are here to help as always.

I would flush flush and flush. Check ph and start over with a mild nute mix and go from there. K toxicity is hard to tell so i could be wrong, but k toxicity will drop ph and creat other defiencies.

Symptom of nute burn is browning of the tips and leaves pointing down. Looks like your nute ratio is pretty high in Nitrogen for flowering. You also said you're overfeeding them. How much of fert do use in a gallon of water (ppm)? Start from there and use the right kind of nute for flowering, the one with lower Nitrogen, my ratio is 3-12-12 at 1 tsp per gallon. Some growers even avoid Nitrogen at flowering stage.

How many more week/s you have to go? If pretty close, just use RO water and ride it out. If a few more weeks then do what 1kemosabe said.

I'm a noob myself so I could be wrong :bigjoint:

i live in iran so the best i could get is this 3 11 38 npk ratio tho i guess i fed it a shitton of the 12 12 36 thing cause it said on its chart to mix like 1tsp per liter
yeah i get the brown or weirdly dark tips then it goes all up on the burnt leaf
i have like 3 weeks tho i guess i fucked it up royally lol
