Hello ! What so you think about my issue diagnosis...

Howdy there @SpinnerGrow! After looking at the plant for a bit and reading your diagnosis I can see the confusion. It appears as a Nitrogen Deficiency on the lower leaves, but the leafs right above them look drastically more green. Almost like the N deficiency set in so fast it hasn't even had time to take from different leaves. At first glance I immediately think "why is a flowering plant showing so many signs of N deficiency while entering into flower?" because typically as you know they reduce their Nitrogen needs as they shift into bloom. Logically in order for a deficiency to set in this quick on a grower who knows how to maintain a PH and proper nutrients its typically because the plant itself had actually massively increased its nutrient wants. My first thought to explain this was a large increase in light to accompany the change to flower. I noticed in your comments you mention putting this girl outside because the LED was to weak after 4 weeks of veg. Was this Before or after the deficiency signs? If this move towards sunlight was made before the deficiency then I think we found the source of her wants. If this move was done After the deficiency started showing then she wanted more N all along and I think we now understand why it accelerated so quickly. (Increased wattage = increased plant growth) Long story short: If the move to sunlight happened before the nutrient deficiency give her some more N - If the move to sunlight happened After the Deficiency showed then give her ALOT more N. 😎
