G `day Stref
I`d go with lower EC more often .
Seems you are getting evaporation more than uptake by the plant . Water is evaporating leaving behind the salts .
So more water - less nutes . And refresh the water more often to keep it from evaporating and concentrating . Also over flow the Hempy`s till you get 20 % run off . eg add 2 litre . run off 200 ml . This will flush out excess salts every watering .
Thanks for sharin
