advanced nute runs hot ?

Never used ph or ec pen in years but found 1 sobi tested my nutes outa curiosity and this is what i get ?

Pants looks healthy as fook week 7 flower. Not tips or curla rhere all lush green
Sensi a b 4ml l
Nirvana 2ml p l
Overdrive 2ml pl

This gives me ec 3.9 ph 6.8.
Feeding to 30%runoff coco 6 feeds a day 3 litre each total

Runoff ec 7.9

This normal? I have no burns but i am scared n peeps say run its 2ml per litre max 1.5ec?

I use 2ml of A & B. 1ml of Nirvana. I haven't seen any reason to go higher.

Usually run those 1/2 recommended dose. Thinking of switching out advanced for that reason alone, just too many part & parcels.

Its due to the chelates humic acids etc i learnt ontop of feed npk so cant read em on an ec

It works so al stick it
