Hi
@budbanditUk! This could be related to: 1) genetics, but RQS strains are usually very good/stable. 2) pinkish light, these are not the best when it comes to the stretch cycle, 3) too much Nitrogen while the plant was in its preflowering stage. There's not much you can do at this stage but bending her or super-cropping her might help, next time be prepared for the stretch and start to LST as soon as the plant has 3-4 nodes, this will help to contain its height while multiplying nodes for a better yield. Hope this will help, let me know in the comments section if you need any further information, happy growing! 👊
