If the run off is coming out that high, you have a salt built up from overfeeding. The plant hasn't been eating everything you have been giving it, so leaving salts behind. This builds up and essentially blocks the roots, and will stop the plant from eating. 

Urgent need of a flush in this case. Flush the medium until the Runoff is coming out below 1.8, as that the level you want it at. Then feed them, and monitor the EC of the res for a while, if it continues to rise, lower the EC of the feed by 0.2

So making an update:

Done flush, extra nitrogen that i have added was caused that big jump in EC not the soil. When flushed, water was coming back with same EC and PH. So we can cross out that from the list, as some extra nitrogen for few days make the plant leafs more green on tops but not below. Nitrogen will be off and i will not add any more for now.

As the flower are growing but i got a feeling that they are not growing with full potential (experience from previous grows). Also now we can see that the steams are weak and they are not able to stabilise themselves  some time i have even notice that they break in half, so that shouldn't happen so we are missing something here. Flowers below the leafs are small and barely visible sometimes as that the unusual thing as well as during previous grows, yes they were small but not like that...

 

Also the flower leafs are turning yellow now, check the photos please.

 

The new thing in this grow was that that i have switched to Canna Booster as its the new nutrient i wanted to tested it, do have feeling it could causing the problems. So i took it OFF and i will not use it any more.

Added some extra Potassium from PK, and EC now is 2.0 - 2.2 for leafs are not burning so will stick with it for now. PH 6.0 

Any advice will be good as i do not have any idea for now what could causing the problem. As time is making a difference here as it is now 4th and half week. 🙁

Canna A&B, pk 13/14 (small doses to support potassium), Cannazym, been using canna boost (but now its without it, before i was using dutchpro booster and everything was fine) and nitrogen for 3 days feedings.

So now im on:

Canna A,B, pk 13/14, Cannazym 

Basicly this table will be good example of how i'm doing it, but of course i'm changing a bit doses to have EC on preferred lvl, as now i'm on EC 2.0

I think its still a bit too much food....even though you bg ec is high, pushing ec to 2.0 is high... lets see how they like the current feed. give it a few days, monitor the run off, and res, if it rises, the feed needs reducing
