MY BABY IS DYING! What on earth is this problem!?

[xMaYHeM]

One day my plants were fine, then almost overnight they yellowed and developed brown dots on all stages of growth.
What on earth happened?
Indoor closet grow 600W light with ample airflow and approximately 28 degrees C.
Pyrmid Purple Autoflowering ~37 days old.
The only nutes that I have added:
two table spoons of blood and bone once per week for 3 weeks
"Trace elements" with a variety of small amounts of nutrients. Most excluding potassium
I water every couple days about a litre and a half to this 1.8gallon pots.
Just before this they went without water for 72 hours accidentally but I don't think that could cause this sort of damage.

I was thinking maybe a K deficiency or cal/mag problems.


Here are a few photos.

She ran out of food. Blood meal and bone meal are very slow working so they were applied too late.

That's a new 1 for me,never seen any looked like that.I want to see what happens now?

 

[xMaYHeM]

Added some miracle gro all purpose ferts as well as some cal/mag with dolomite lime in it to correct the PH.
I only did like 1/4 strength, will see if there's any improvement and if not, I will feed 1/2 strength in 4 days.

one thing that blood and bone has is potassium 1 hand full does me a hole grow for outdoors but i only use in flower it a could be the ph has goten to high from the blood and bone or u have cooked it or its got root rot best thing i could say is flush and feed it some kelp or fish exstract and leave it dry out for a week

keep feeding it super thrive or rhizo for the next week or 2 till it goes green unless u can get to a hydro shop and get go green or dr fix

this is potash burn same kinda burn as your just a diff product and i just flushed that shit out and it turnt out wicked leaves never recovered tho

I suspect that this is actually over fert. 2 tablespoons? every week for 3 weeks? too much. it also looks like the air temp might be too high. no more fert for a while. transplant into a 5 gallon bucket. happy frog soil and don't add fert.

 

[xMaYHeM]

Damn I thought it was a potassium deficiency not a toxicity.
So I added more haha shit.
I am going to flush the shit out of it in 2 days.
About 50% of my leaves are fucked.. I've pulled a lot of them off
They look better after a clean watering last night and a watering with miraclegro maxfeed and some calmag a few hours ago, but I will keep monitoring them closely and update this when I see changes.
Thanks rob

Are you sure about transplanting them?
I'm thinking about it; but they're autoflowers so I'm not sure if it's a good move.

 

[polishpollack]

transplanting won't hurt. certainly not like 2 tablespoons of fert. you might want to give them a water flush first, 2 gallons worth, let the excess water drain out, then transplant. it's easier to transplant when soil is dry because the volume of soil shrinks and it's easier then to pull the soil out of the pot.

So my plan is to flush tonight (12 hours)
Then wait until it's completely dry.. Maybe 3 or 4 days, then transplant to 5gal pots.

Sound good?

It's my first grow, thank you so much for your advice

Blood meal takes 3-4 weeks to activate in the soil, and bone meal only needs adding once per grow.

 

[xMaYHeM]

man, they came back really well so i didnt want to transplant them after flushing
suddenly again over 3 nights with no nutrients added since flush, all the leaves appear as the super sad leaf in my original comments last pic

my other plant is getting red leaves, some around the edge some in the whole middle of them. Am currently researching
Would super appreciate if anyone knows anything
peace

 

[polishpollack]

hard to say. this plant dies naturally after many weeks of flowering. looks like you gave too much fert too. looks like it's more than one problem. what soil is that? 28C is too warm. that's about 87F which is way too warm. ideally no warmer indoors than about 22C.

 

[xMaYHeM]

Adjusted the temps a week ago to be a solid 23-24 and it's canna terra pro with about 30% added perlite
maybe it's just too late and maybe theyre just dying naturally
Oh well! 15-20 days left anyway! Cant wait to smoke my first harvest, even if it does end up being shit

that's the spirit brov, take the lessons it teaches. Learn from them, then get on another and continue the process untill your a master.

Pack it with as much compost and mulch as you can fit into the top of that container. Then water in a quart of water with a 1/4 tsp molasses dissolved into it. You don't want run off.

This should perk it up in a matter of hours/days.

Wow, did you ever actually transplant these while weeks into flower? It is natural for flowering plants to dispense there leaves. Transporting nutes from the leaves elsewhere to were they need to be. You also look like your over fed which resulted in nute burn and the yellow from flowing. Just looks like a lot of yellow at one time. How are they doing? You should really get some super thrive. Ppl live by that shit.

PolishPollak said it pretty well natural dispense of the plant with slight over feeding and the high temps.

Can we please get a updated pic of this !!??!!??!!??!!??
