Mongodudu is right, your girls is needing some cal/mg but dont just add on top of your other nutes. Reduce the other nutes ppm by the amount ppm of cal/mg your gonna give. Cheers

Magnesium mate. Calmag should help her out, if the pH levels are correct 👍🌱

N starts with light interiors and dark edges and before making two floors there is already at least one yellow leaf usually, so that's not your case in my opinion, and man if your calmag is 8-0-0 is shit in my opinion you can't use it in flowering

I'd say Nitro, But i'd also use my CalMag, because it's NPK 8-0-0. May you have a look at yours. Good luck🤞 Servus OimRausch

No N, go with calmag to enrich the soil with cal mag and micronutrient
