Plant dying at 5th week of flowering

[Borjaazul]

Hello, I beg for some quick help. So the thing is I have 2 bubble gum plants at the time in 12 litre (3 gallon) pots. I am using soil and they are now 4 months old, 5 week of flower. I have been feeding Advanced nutrients BLOOM, and CalMag at the indicated dosage according to the bottles. I am using tap water dechlorinated for 24 hours and pH at 6.5. I water my plants every 4 days or so, depending on how dry the soil is. Mostly, the bottom leaves are turning yellow on the veins annd then dying not so long after. It all starts on the veins, and the some thick sports occur and the leave is gone in 2 days time. Please I need help urgently.

Light info (16000 lumens for a 2x3):
1.cfl 20watts 6400k
2. 2x led 15 watts 6400k

Take a picture of the whole plant and give light and tent info. Just use this same thread don't begin a new one. Less confusion

something missing here can't think what it was

Updated, thank you so much for you reply

best solution and easiest is just pot up to the next size with fresh compost this time add 25% perlite no nutes 2-3 weeks
or until you see upside

12 liters it not much for 4 months old plant, in that size in week 5 of bloom.
I’m with Vostok here. Need a pot up, not ideal in flower phase for sure. But it’s not big.
What about the drainage in that pot? When it takes 4 days to water again, it should be drinking/eating a lot in this stage.
And it also looks like You have nute burn when I zoom in on the whole plant, many tips are burned, not just on the main leaf.

If it were me I would get a bigger
pot. Then after she settles in I’d trim the lower ones that are yellowing right off in case it spreads. Or you could trim
them
and then transplant she
looks big and healthy so she can probably handle
it, mine did.

 

[Borjaazul]

That is right, although the nut problem was covered, looks like it was ph problem as it was solved with a flush. Pot and drainage will be improved for sure haha. Thanks a lot!!

 

[Borjaazul]

Completely right, I will do so for the next plants. This one looks better now after a flush

 

[Borjaazul]

Defo, I have to add a lot more perlite for now it looks like its able to live. Begginer issues... Thanks a lot!!

 

[CaptainWiese91]

It doesn’t help to just cut leaves of and the spread will stop. You need to find a diagnosis first or else the spread will continue

what if you ....kept the faulty leaves and used them as 'control points' like the pros do...?

 

[Xconian]

I don’t know anything about that, do explain please

 

[vostok]

at risk of hijacking Borjaazul's thread and suffering yet more abuse from @alltatup I decline

but urge you to google for now

cheers

Xconian I'm not sure if vostok and I are talking about the same thing, but I keep damaged leaves on the plant as a way to tell if problems are getting better/worse. Leaves that are already damaged tend to get it the worst, so they're a good "canary in the coal mine" so to speak.

 

[Xconian]

Ah gotcha that makes sense
