You're right on point, bubb. Your girls will pull their (n) reserves from the foliage. And she'll become more sugar coated as time passes. Don't be alarmed of yellowing during flower, this is the girl's natural transition for furthering the potential progeny/flowers before winter. But remain weary about nutes vs lighting. Nute directions are typically for 1k HID or sun in the labs w/ the R&D notes.

Edit: BTW I really like both spectrum's with the WW. Harvested at clear:cloudy 75:25 and all amber. She's has a screeching creeper high at mostly clear, and a really, really, good body effect while 90% amber.
