What's the problem with her? :( 30 days old, in soil 6L, temperature around 26-27 C, 60% RH, water ph is around 6.8 and nutriments: BioBizz Calmag, Canna BIO Vega, Rhizo. Watering every 2 day with 500 ml. Thank you very much for your help! ๐๐
By look lack of phosphorus.
At least my first idea was that.
Your diary is old, but if you have still same grow in coco, your npk ratio is wrong, or you entered flowering stage ang girl needs more PK part aka bloom fertilizers.
