Day 72: Welcome to week 11. Today I realized some more damaged leafs. I'm not sure, what it is. I've to ask here, now. But as I saw this and also, that the EC within the soil is increasing, I was thinking, that she is not able to consume the nutrients correctly. I checked my PH meter and I calibrated it wrong last week 🙈 So she got the wrong PH for about 2 days. I hope with the corrected PH, she is able to take the nutrients again. UPDATE: Thanks to everyone who answered my question. I have done 2 things now. I lowered the level of the LEDs to 7 in AC Infinity Controller 69 Pro to give less intensity to the upper colas. Secondly, I added some CalMag to the reservoir. I also added some distilled water to adjust the EC level and then checked the PH level. Day 73: For now, it does not look worse to me. I refilled the reservoir and adjusted the PH. I increased the CalMag Agent from 0.6 to 1.5 ml/L. Day 74: I checked again the symptoms and as I was feeding the PK booster to long, I strongly have to assume, that the CalMag issues she is showing, are the symptoms of too much PK for a too long time. I decided to clear the reservoir completely and added only a bit of CalMag to plain water and adjusted the PH. Day 75: Today I got a new and more reliable PH meter. It turned out, that the other one was still calibrated wrong and with that information, I assume it is a combination of the wrong PH for days and too much PK for too long. So, I'm happy, with my decision so far. Next time, I'll have to make a note, wenn to stop with the PK posters ☺️ Learnings over learnings. Day 76: Today I was able to take some photos and also a video, to show how she looks now. Not too bad and I also checked the trichomes the first time today. It's looks like she is almost ready to harvest. I was aiming week 13 and with that tiny mistake, I guess she is ready someday next week (sorry, for the bad photo of the trichomes, I was not able to get a better one 🙈). I cleaned the reservoir and filled it with plain water @ 6.4. -------------------------------------------------------------- You also like to get some seeds from Fast Buds? You like a 15% discount?
