Hello,

Electrical conductivity (EC) is a measurement of the dissolved material in an aqueous solution.

It will increase depending on the amount of fertilizer you gonna put.

If I remember correctly they start the flowering at EC 1.8 and they will flush 2 times between week 2 and 5 at EC 1.3.

Check on the videos to be sure.

 

-Peace.

yes, the grow videos are a bit confusing,  you must remember they have starting EC of 0.7 from tap water in the videos, it says in the scrolling text and also in the powderfeeding guides. because the water is already very hard there is no calcium in the pf and possibly lower amount of other micros that come from tap also

so when they are flushing they add 0.5ec on top of tap and 1.1ec on top of tap when feeding

 

i personally keep my feeding around 0.8-1.1~including the tap ec of 0.14 maxing rarely at 1.2~ and dont see the need to flush as plants use up reserves naturally too just like it happens outdoors in fall without the need to waste anything in drain

 i start dropping food at right moment gradually, finishing with just ph'd water assuming i have used right npk's but than again i have 3-part nutrients so the npk can be adjusted as the plant requires, the plant uses reserved nutrients just fine when feeding conservatively and according to plant needs

 

also the explanations&reasons i see for the flushing schedules/routines do not follow any kind of scientific research/results or the biology of plants we know from hundreds of years of scientific research, so i reserve washing my medium for the times when there are real buildup issues in the medium or roots and i will do it with natural beneficial bacterias. as it is huge waste of resources and time to do it, it harms the planet and is overall completely pointless procedure with healthy growing plants

About us

Strain Hunters is a series of documentaries aimed at informing the general public about the quest for the preservation of the cannabis plant in the form of particularly vulnerable landraces originating in the poorest areas of the planet.

Cannabis, one of the most ancient plants known to man, used in every civilisation all over the world for medicinal and recreational purposes, is facing a very real threat of extinction. One day these plants could be helpful in developing better medications for the sick and the suffering. We feel it is our duty to preserve as many cannabis landraces in our genetic database, and by breeding them into other well-studied medicinal strains for the sole purpose of scientific research.
