Platform has chat. Right bottom corner, press arrow.
She is very far from harvest. At least in diary photos. Dont believe breeders recommendations.
You can feed her few times still.
Ph would be two letters constantly repeated if i would wrote a book how to grow weed in soil. Ph is everything here. Then goes rest.
Autos dont like many food. Excessive nitrogen, potash, and many more complicated relations can block calcium absorption, but wrong ph is most common mistake, then goes overfeeding.
I would do two plain waterings for her, with 6.3 , dechlorinated wateter. Only after 9-10 days ( or what ever it takes for 2 wet/dry cycles ) i would return to feeding.
Want to be on safe side, add 0.5 ml/L of calmag to second plain.
Thats what i would do.
Honestly from look she has 3 weeks, maybe 4 till earliest harvest window.
