Nah it wasn't the screen. It was my first coco run coming from soil. Didn't expect the stretch hahah. In soil the most I'd had was around 30-40cm but these went atleast a meter and they were 20cm off the lights, couldn't get in the room to prune, didn't do the runoff properly and ended up with like 4.8ec runoff, room temp was around 32C , they hermed plus numerous other things, was a complete cluster fuck but still got my PB hahahahah seed was barely noticeable just a heap of nanners
