Pineapple Express. First grow (second try). Coco

FUCKING NONAME MYCORRHIZA! As I wrote before, I added mycorrhiza to the coco coir from a local store. It turned out that there is slow release fertilizers in it. But this was not indicated on the packaging. 6/02 In the evening, I decided to water the plant with a concentration of 450ppm and pH 5.8. From the drainage I got 700ppm and pH 6.7. I did not flush, as I was very tired, and I watered the plants at the end of daylight. But on 7/02 in the morning, I still decided to do the flushing. Poured 1.5 liters of solution of 450ppm and 5.8 pH in 7 approaches until I reached 460ppm. But pH still remained 6.6. I don't know how it will affect the further development of the plant, but I don't see any other options yet. I washed the coco coir with a lot of water before use and then soaked it in water with fertilizers and leveled pH 6.0, so this is definitely not the problem. Update: After researching the issue of pH, everything became clear to me. For coco coir, it is important to adjust the pH of the watering mix, and the pH of the drain is doesn't matter. Only the ppm level is important. There is an interesting article about it on CocoForCannabis. The plant reacted perfectly to today's (7/02) flushing. I want to note that I did not flush with clean water, but with a mixture for watering 450ppm. Now the leaves have risen up and the slight yellowing in the middle has completely disappeared. INTERESTING FACT: you can get a deficit due to high humidity. It also works in reverse. In short, at high humidity, you need to make the mixture more concentrated, because the pressure between the steam in the leaf and the air is lower, accordingly, less water with nutrients reaches it from the roots. Thank you for attention🙏 Peace🙌
