Fan leaves dying rapidly - before flowering has started

Hi guys, getting a bit worried here, I'm growing outdoors, keeping it fairly simple, nice rich, airy soil, plant had been growing really well, 8 weeks of vegetive growth, just having first signs of flowering, but fan leaves dying rapidly now. Haven't done anything differently, so I'm really lost as to whats happening. Any advice would be greatly appreciated! Thanks in advance..

Ph problems are the most likely cause.... what is your ph on entry and ph on run off..

Also what are your temps at night and through the day

I need to buy a ph meter asap. Temps are 82-86 during the day and 75-79 at night

Temps are fine, but you need to test your ph it looks as though it has nutrient deficiency caused by ph problems

Actually I have a meter but not sure how accurate it is as its a bit old, its saying 7ph in the soil. I watered it earlier so run off is all gone.

OK what nutrients are you using tofeed

 

[GoldenGlow]

The soil was a ready made mix, with different manures etc, its quite strong smelling, so I guess its full of power. I've just been adding a dash of worm juice to the watering can. Today I added some potash liquid as its just starting to show some signs of flowering.

Your plants still needs certain nutrients to survive and this far on into plant growth it's probably used up all Nutes that it needs and is needing more

Damn its a hungry plant! So worm juice isn't enough, what would you recommend? Also the pot is 3 gallon size. I did the LST with the plant, its grown well, bigger than expected so maybe its size is consuming more nutrients than last time, cos I grew under similar conditions without this issue..

Also thanks for the replies, it's my only plant for the year, so I'm freaking out a bit lol

Here is the plant looking healthy from above

The plant looks really good actually from this picture doesn't look as bad as I thought I wouldn't worry about it for now if it's only the lower leaves it usually be fine as the plant is drawing in all its energy for flowering sometimes the lower leaves get left and the odd few will die off

 

[GoldenGlow]

Ok, so hopefully its doing just that, drawing the energy. Was just worried at the pace of dying leaves, hoping it wouldn't keep spreading.. Also on second close up pic of dying leaf, there is a strange dotted pattern, wondered if that might mean anything?

Looks as though it maybe a little cal mag deficiency but doesn't look major if it's just the one leaf just keep an eye on it or I you have some give some cal mag supplement
