Purkles RP Sour Diesel Quantum Boards

Things have been going well as I continued to train the stretching girls to the side of the pots, bending and adding ties where needed. Pheno 1 started showing signs of over watering showing droopy leaves as well as what I think is either nitrogen, magnesium or iron deficiency. I'm leaning towards a iron deficiency since the yellowing is on the newest growth at the top. I think this was caused from giving her too much top amendments in her last feed causing a pH imbalance. What I would usually do is just give her a little flush if this is the case but instead I decided to repot her and the other Pheno into their last 19 litre/4 gallong pots as both were drinking pretty quick and I wanted to avoid over watering again. The rootballs looked beautiful when I transplanted them so I was pretty happy with their progress! This round I've ditched the coco as I had way too many issues with it in the past, including knats and PH issues. In this round I've gone with Biobizz light soil which I added some fish blood and bone, earthworm castings, bat guano and then watered with water and liquid seaweed. I love organic growing :). I do intend on using Coco again but I'll need to do some research on some trusted brands. If anyone has any suggestions please let me know! Pheno 2 is showing signs of recovery but I'd love the input from others about what the deficiency could be? I got my new bubblebags today which is making me want to flip to flower so I can get to harvesting and making some bubble but I'm going to be super patient this round. I want these girls to fill up as much of my 4 x4 tent space as possible. Until next week! ✌️
