Yeah, and whenever you have that intake pH take some pictures without flash, I'm having some difficulties understanding their colours.

hi there folks sorry it took such a long time but I've had a few family troubles over the last week, any way here's the pics and info requested.
I measured the ph going in and it was 5.0 so that was a bit low.
I've just changed over to flowering nutes now so hopefully that will help I've measured the ph in at 6.0 now and the run of is around 7.0 so hopefully this is better all comments and help welcome, check out some new pics in natural light as well.

Hey aaran,
Your pH is above recommended line of around 6.3/6.5. Feeding at lowered numbers might help improve your soil conditions, but it's a slower fix. Flushing with half amount of water at 6.3 will improve your soil's condition and start the healing process.
It looks a lot like Early Leaf Spots funghus. Are those spots a lighter shade of brown on the underneath of leafs? If so, it will not be easy to erradicate, I tell you. There's no quick fix for this.
There are several types of leaf spot funghi, and each manifest differently on the shape and color of spots. The spores travel by air and usually infest the air system environment. It's relatively common that the funghi spores survive within seasons.
You'll need to improve your air flow, removing the infected leafs is advised as it will improve the air flow and remove troubled leafs. They need to be discarded. There are a few solutions you should try to see which fits you best: neem oil is more preventive, garlic solutions are both preventive and health enhancer, baking soda is known to have been used but it does add sodium to your environment, Seaweed hardens the leaf surfaces, Citrofresh as shown some results on erradication and also Copper oxides.
I recommend you take a good long read at this thread over here:

There are several other resources online as this is somehow a common problem in many crops: http://jnkvv.nic.in/IPM Project/disease-groundnut.html#Late_leaf_spot_
IMO it's not a nute problem. It's also unluckily pH to be the only culprit. If any other grower would chip in it would be great
Ps - thanks for the trust Kush

all new growth is coming in with holes in it now the plant has no brown marks but continues to get worse its beginning to look like a lost cause.
any major remedies, solutions ideas are now welcome as it now looks like fungus.
thanks hugo for your help on this do you think there is any hope?

I've not seen anything like that before but I would suspect insect damage over any kind of a pH or nutrient issue. I would give them a close inspection and probably treat with some neem oil.
last year I saw something similar on 1 of my Auto Assasin, the spots started out looking like "splash back spots" from watering too fast under hot lights. mine were crispy around the edges of the holes. The underside of the leaf had black spots. they had almost a velvety feel to the spots on the underside of the leaf. since we were in full flowering,(week 7) I just plucked all the fan leaf and let her finish. I dont know if the spots effected the taste though because we used that entire grow to make canna infused coconut oil med caps. I can tell you that the spotting ruined alot of the leaf we use for raw canna leaf smoothies,not wanting to chance ingesting them raw.

I just picked up some of this stuff at home depot. I haven't used it on canna but I did use it to kill off a fungus problem I was having on my tomato plants and, a week later, still no signs of fungus and it was gone by the following morning after application. I'd sure spray some on my cannabis plants if I had the kind of problems you're dealing with.
