Yes ec is mS/cm and the ppm conversion is using a .5 scale. MicroSiemens per cm is μS/cm Happy Growing

How to control EC
My EC is higher then recommended or I'm reading it wrong. I have been told to add water to my reservoir to lower EC, yet with my well water the EC is already high. Can someone help enlighten me? Using a hydroponic circulating system (DWC with a top feed).

我的女孩怎麼了,這個是生病了嗎?還是太多的餵食?
在他長出第二對葉子的時候這樣的現象就出現了,但是只有一邊有葉子,我查了相關資料顯示這是菸草鑲嵌病毒(Tobacco mosaic virus;TMV) 我覺得挺像的。但是不是很確定,我該繼續等幾天嗎?還是把葉子切掉。 誰可以告訴我解決方法,希望他可以度過生長期,因為他是自動開花,每一天都很重要。

Autoflower PPM Requirements - DWC
I have found this plant's water/nutrient intake is equal at 350ppm right now - end week 5. I am beginning to feel after several auto grows that the ppm requirement with GH nutrients is WAY less than what the web serves up? I doubt I can push this one beyond 500ppm? (0ppm water)
