Mid Flower Problems

[TD.]

I need everyone's collective help on this, please.

Sorry for the blurry pic.

This plant is half way thru flowering.

Leaf matter turning yellow around the top and middle of the plant, then shrivels and dies.

considering all the background you have given us on this i would guess that these plant/s are genetically predisposed to this behavior and is no cause for alarm ...

presumably plants have only 4-5 wks to harvest and any new growth will be flowering heads .. leaves are giving up their sugars, starch and chlorophyll to be used in the production and completion of flower formations .. this is much easier and quicker for the plant than producing new building blocks to produce flowers .. plant is naturally in decline, its life is near end ...

 

you did say you only wanted 2c worth

my 2c is on overferting

Sort of leaning towards the above post with overfert or salt buildup or both...what is it, soil? Have you flushed the soil at all during it's life? Once it gets to that stage it'll show as all sorts of issues from over fert, to nutrient deficiencies to looking like pH outta whack even if it's not.

 

Some leaf looks like it's sucking all the nitrogen like in the bottom left hand corner of the first shot like it should in flower, but the others look burnt.

 

I'd reckon a good heavy flush would be an idea, then follow up following days with a flush before feeding

 

 

That's not your super skunk by the looks of it?

 

 

More info and more pics.

problems cant really be diagnosed with such little information...

 

what are you growing in.. what are you feeding it.. what sort of system...whats the PH and EC levels.. ??

 

all these need to be answered to give the right diagnosis...

 

looks to me.. a PH issue.. which is causing a nutrient lock out.. maybe built up salts..

what are you growing in.. what are you feeding it.. what sort of system...whats the PH and EC levels.. ??

 

feeding canna nutes

using a DWC (dissolved oxy is high)

ph between 5.8 and 6.0

EC before everything went funky was 2.0

now lowered to 1.4 for the last 9days ....been flushing every few days.
