I measured my ppm it is 400, but my EC reading are...

EC and PPM are the same thing , they just measure out differently its the math formula that makes it so . If your EC 0.xxxx is double the amount of your PPM then you have the proper reading . Its tricky to understand there are a ton of formulas out there that will explain it . Here is what an EC chart might look like just to give you a quick comparison to what you might be looking at . You might also wanna keep in mind that there are various PPM equation for various PPM readers as well , so you might wanna look into what formula your PPM meter follow's . Here is a link to a chart " https://www.bluelab.com/knowledge-base-files/Conductivity-Conversion-Chart " This is a very accurate pen and the chart is well made as well . The last thing I might suggest is that you trim back all the damaged leaves I can see in the pictures to prevent any unwanted pests from making themselves a nice new home . Other then that you're well on your way to getting some nice medicine ! - Happy Growing!

You should choose one of these measuring unit because they are both referencing to the nutrient level in your water and they are both referring to the same amount of nutrient , it is like the inches and the centimetres 😊✌️🏼 I prefer to use Ec

Hey there so your ppm and ec are pretty much measuring the same thing, water should be in the range of 0-400 based on what kind of water and quality and then once you add in nutrients it will raise that to somewhere around 400(if you have a 0 for water) up to 800 ppm...i think that's kind of the range you're aiming for. This info can just help with knowing if the plants are going to or being burned. So if you're not adding any nutrients right now...your water fairly high. They make nutrients for high water (or hard water) so that may be worth looking into. Happy growing ✌️

het Covik la flaire, so basically 400 PPM is equal to 0.800 EC, one measurement is from america, the other measurement is from europe. Simple as that. So if you dont know why you should measure EC let me explain , simply EC (electrical conductivity) is the easiest way to measure fertilizer levels. "EC is the measure of total dissolved salts in a solution, the factor that influences a plant's ability to absorb water. EC is a meaningful indicator of water quality, soil salinity and fertilizer concentration. Therefore, knowing EC levels can help plant production and lead to more cost-effective use of plant inputs and less shrinkage. The presence of high salt levels is a sign that adjustments are needed – before damage shows up in plants." So you're at 0.8 EC, and that means you're in the perfect range for seedlings and young plants. Dont change a thing, you're good ! hope this helps ! 🚀
