@Growlecule, wow, thanks a lot for the very detailed answer😊 First of all, this is the second nutes feeding for this plant (first time I didn'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'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'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 (<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'm starting to get a bit worried that something's wrong. Will keep you all posted 😁

Hi growmie!👊 First of all, great job buying some meters, you will be rewarded in buddz and knowledge✌️ Your tap water reads 280ppm, thats normal, little high maybe, tap were i live is around 290-320ppm which is considert high. It means that: if your goal of week 3 is around 350-450ppm, you cant add alot of nutes. So you need to either dilute your tap with RO or rain water or such, or go for bottled water, if you like to add more plant specific nutrients. You are still in range with your 1ml added nute so continue. Remember this applies only to either coco/hydro or soil mixes with a little to no nutes in it. Organic soil mixes dont require extra nutes with autoflowers, and only need pHed water and a occasional watering with run off to wash out excess salts. So for your method: first add your nutes then apply a ph correction not the other way , your nutes will effect the pH of your solution so you need to adjust it after you dissolved your nutes into the water, thats why your pH is that low, probally fed with a low pH water, try it on your next watering growmie. Your EC and ppm are to high but, if this is your fist serious run off that shouldnt be a suprise because without run offs every now and then, you will collect salts in your soil, this disrupts the roots from absorbing water and nutes( its called osmoses it happens in the plants cell walls ) So now you look at your plant: does it has burnt tips( first sign of high EC ) ? No you dont, so either your ppm meter isnt calibrated, i suspect it is cause of your tap water reading which looks fine. So your plant is still okay with it, but for how long? If i may suggest, i would water with at least 20% run off the next at least 5 times you water, add that 1ml of nutes per liter and youll be fine, measure your runn off and get closer to 500ppm or 1 EC. You can always pm me gromie😁👊

Hi growmie @cuchillo, Just a quick thing, your growing a autoflower which needs less nutes than a photoperiod cannabis plant. Your runoff sets at 900 when you feed less then 400, this doesnt mean your in your sweet spot. It means your soil contains far more than 900ppm. 400 in 900 out, your water has taken up 500ppm extra, meaning you are well above 900ppm. If your unsure of your tds meter, use RO water, this always reads 0-10ppm and you know your good to go😁👍
