Your plant peaked my interest to learn more about growing in coco. I've always used soil, but it seems like if the coco is not buffered/charged it can hinder your growing process. Coco is neutral, so no nutrients. By buffering with cal-mag this should would give your plant a head start by providing it basic cations/nutes, being soil is pre-made with starter nutes. Coco is suppose to hold more water better than soil, to where you should not need to water as frequently. I didnt see anything in your diary regarding buffering/charging your coco or what kind of coco you are using. Your plant looks overwatered and not getting a specific nutrient from the coco, which is causing a nutrient lockout. I would also start your next grow in a smaller container to control your watering. I hope this helps. Also I would flush it if you haven't and let it mostly dry before adding anymore nutrients and water. MJ coco if you want to learn more. https://youtu.be/NzpI856R87I?si=o0HNSHhp0Q0BV2VY

Good luck in this grow! Just like life, its usually trial and error. Research as much as you can. Monitor them, I lived in my grow room at the beginning of my grow journey. Now, I can live life while they grow. One week at a time! FYI distance and intensity of your light maybe off, maybe a stronger light or pull the light up, not to close to where she burns will help those nodes space out a bit, other than that she looks good. Yellowing could be a imbalance ph or overwatering. Water less and bring your light intensity down giving, too much power can hurt her at this stage, yellowing and could stunt her, She will grow well by doing this. (edited)

Im growing gdp also. Coming up on week 3
