Salt burns, water used to transport nutrients accidentally sends fragments of salt if the medium is overfilled with salt. Salt gets trapped in epidermis where it burns surrounding chloryphyll.

Hi, überprüfe unbedingt deinen pH wert… Bei falschem pH wert kann deine Pflanze kein Calcium und Magnesium mehr aufnehmen = Nährstoffblockade Wir haben das selbe Problem aufgrund eines fehlerhaften ph Testgerät. Haben jetzt den ph wert im Wasser angepasst und die Ladies mit ca. 4l angepassten Wasser „gespült“. Zusätzlich gibts absofort calmag Dünger Beste Grüße und happy grow!!

Check your pH. Keep it between 5.8 and 6.4. That's the start of what looks like a Calcium deficiency. The question is, why? Out of range pH? Lack of supply, or Locked out due to too much potassium, or salt built up in the medium. If you are growing in Coco and you aren't using a specific calmag additive along side your nutrient line, i suggest you go get something like General Hydroponic's Calimagic, or some other calmag additive. Every nutrient line has one...take your pick. And if you aren't adjusting your pH when you water, and have no ability to, then you need to get yourself some sort of pH tester so you can setup your water before you water in.

Flushing don't seem to solve my lockout It's been 6 days since I noticed the problem. first thought it was a deficiency but really is a lockout. I flushed 2 days ago but she keeps getting worse. Am I being impatient? I flushed with tap water pH 6-7 until the runoff was in the same range and haven't fed her for 4 day.

Weed doctors to the rescue Day 44, fb auto, my happy girl developed those dark spots at the top... Is this a Calmag deficiency? Although I'm giving her calmag every feeding. I think there are also first burnt tips. I'm about to water her tonight, what should or should not give her? Thanks for your inputs🙏
