If you were growing in an inert medium instead of a soil mix measuring becomes easy but in soil you have many variables (even if you make your own recipe) as the soil has nutrients of its own and when you water solids and salts could be making your readings higher after going through your substrate.
I really only ever used my TDS meter in closed-loop NFT, or flood and drain type setups (1400ppm was my sweet spot for my White Rhino but my Incredible Bulk likes nutes a bit weaker, 1200ppm seems OK) where the nutrients are used for a couple of weeks before swapping for fresh.
Hopefully someone with more experience with dirt can chime in and help you.
Wow , there is still a lot I can learn. I have just googled NFT: Nutrient Film Technique. I hadn't known of its existence. I only knew the terminology "soil, coco & Hydroponics" though I actually still know only soil and to be honest this is even the first time that I have used Perlite, which means that even speaking of soil I still don't know everything.
Anyway, from your answer I seem to understand that my considering illogical/hard do comprehend the explanation of that guy on Youtube (see my last posting) is justified. In fact, I thought that his three scenarious as a result of measuring/comparing the value of the feeding water with the one of the run-off water could make sense only if I was using hydroponics.
I would still like to find out a reliable method to measure the ppm thus make sure to monitor the right amount of ppm avoiding both the underfeeding and the overfeeding when growing with soil. Maybe there aren't but it is anyway a learning process. I might opt for hydroponics or NFT for my next grow!?
[That could, by the way, be an other interesting topic to discuss in the future: The advantages/disadvantages/differences of growing with soil, coco, hyproponics and NFT.]
Soil is a great buffer for many things...
Id worry less...
Get temps down..
When experiance comes you will know from your plants if they need more or less nutes..
Yes, it is very exciting learning so much. Believe it or not I am enjoying it , though sometimes I am worried about my three ladies...Well, you have all got it that ......I have no and I am looking forward to
Although the idea of growing your own plants is quite obvious, I had never really considered it. For that, I am very grateful to XX here in this forum for getting me do it.
By the way, today I removed a couple of yellow leaves which appeared to me like a waste of energy for the plant. Ultimately, we all aim at flowers not at leaves, don't we ? But of course I am still not experienced and don't want to do a lot of defoliation yet.
By the way, one of the three ladies (Shoko) seems to be starting flowering already?! Isn't it a tiny bit too fast? The other two also looks moving towards it but they aren't yet.
I cannot consider it as the flowering stage already, can/should I?
