<span class="link_user">@cuchillo</span>, Hi App is FlowerCare and device is FlowerCare to. Hope this helps

<span class="link_user">@Growlecule</span>, wow, thanks a lot for the very detailed answer:blush: First of all, this is the second nutes feeding for this plant (first time I didn&#039;t have the meters), and have used the same info to give the first nutes feed to my other plant. Both plants have been planted in 9L of Biobizz Light Mix - which, from info gathered on the producer&#039;s website, should have sufficient nutrients for 2-3 weeks - and both plants look very healthy (to me; see pics for more details). As for the EC meter, I did not calibrate it and it doesn&#039;t appear to have a function to do it; the manual as well does not indicate the possibility of calibration. As a reference for ppm, I have been using the following RQS post: https://www.royalqueenseeds.com/blog-cannabis-water-quality-part-2-ppm-ec-n298 I was therefore aiming for a ppm around 850-950 (judging from the table provided in the link above), and in order to avoid any major mistakes I kept the ppm of the solution I gave to the plants fairly low (&lt;400). When I read the run-off results (pH 5.41; ppm 925; EC 1850 micro-s/cm) I was quite happy, as these values are in almost-perfect range when compared to the suggestions/guide I found online. Now however I&#039;m starting to get a bit worried that something&#039;s wrong. Will keep you all posted :grin:
