На органике это мой первый полноценный опыт. Хотелось бы знать, имеют ли смысл замеры ppm/ЕС субстрата на выходе? И почему за трое суток так. Тремительно вырастает PH?

Nute burn or something else?
My middle and top leaves are yellowing from the tip and edge inward, is this the nutrient burn or another issue altogether? Runoff PH was 5.9 and ppm was 700.

pH very low (5.0) but plants seem to appreciate it!!
The pH of the reservoir is lower than the perfect range (5.0) during flowering stage for almost 2 weeks but plants don't seem to suffer. They are growing very fast. Should I change it or leave it if they seem good?

Nutrient problems I cant identify confidently as I am a noob
Hmmm, I've got some nutrient issues by the looks. Is that dark splotch on the leaf indicating phosphorus deficiency? My pH is OK. Looks like a few things are going wrong. Thanks!!

Friends need your help! the leaves turn yellow at the seedling stage!
Friends, help me figure it out! First I will describe my conditions! - Tap water 110 ppm - LED QB288 Rspec 250 Watt light works at half the power! - Advanced Nutrients three-component Fertilizers Micro Grow Bloom now I'll tell you how it was! after they have sprouted! they were planted in the system! I made the solution on the recommendation of the fertilizer manufacturer! I added 1 ml/l of each component and it turned out 410 ppm! The second week I changed the solution completely and added 2 ml/l of each component, it turned out 600 ppm the yellowness on the leaves appeared after the first week! I thought it was a magnesium or iron deficiency! and I changed the solution and added 2 ml / l of fertilizers! I keep the ph of the solution within 5.7-6.0 drip irrigation works constantly! The temperature in the box is 23-25 C - humidity is 40-60% Inside, there is a fan on top that turns 360 degrees to blow the plants!
