Nothing to be sorry for man, I been using Advanced nutrients PH PERFECT, but with half dose, let me show you some pics of her neighbor, same thing but on early stage
4-5 days gap between watering man, root seems ok when I transplanted her. Most similar diagnose I found online is phosphorus deficiency, but nothing sever like mine :(
This is my 7 weeks old baby, got stunted from root bound when she was little, after transplant to her final 5 gallon home, this happened immediately. Pics below are from day 1-3, shit when down FAST. Always keep my pH between 6.1-6.8, can't find any thing online similar to this. Feel like she is...
