It already has its preflowers, and you should always green clean, no matter what stage. Because that one fan leaf you took off was covering something else that is not getting light. Fan leaves are only there for growth, support, and storage of nutrients. If you pull too many fan leaves your plant droops because it lost that support and or balance. By pulling them off during veg, you're causing your plant to react and fix the problem. Green cleaning ultimately leads to healthier stocks/branches, bigger and thicker, and allows the inside of all of that shade to photosynthesize.
Just my thoughts
i grew that way for many years with huge success but through the process realized over the years that less veg defol and more well thought out pruning throughout flower led to to less deficiency problems as nutrient stores from veg were abundant to sustain flower without any loss in leaf colour right to the finish my plants never yellow at all they are green from start to finish and ph checked and adjusted twice daily , no lock outs ever and smashing results .
Your girls are looking great
