cr8grow’s Cream Mandarine XL Auto Grow 3

Day 42...end of week 6 from sprout. Several days ago I replaced the 4k bulb with the 3k flowering bulb. Last watering I went one day too long and had wilt on the tallest...they all recovered well several hours later. I also switched to flowering nutes. New feeding routine 2 total gallons PH 6.5 water across all four plants until run off. Biocanna BioFlores 2.7 tsp./gallon, Budswel 1 Tbsp/gallon and 2ml TPS organic CalMag. The tip nute burn is from my last veg feeding. This week the leaves went from green to light green almost overnight. This is my first auto, so assuming just normal fade with 3-4 more weeks until harvest. I will water and feed again tomorrow and will keep an eye on them. Im good with the plants consuming the fans, but hope at least some make it to the end. The flowers are stacking and swelling nicely, the calyxes looking like they will be large. The smell is skunky fuel now and I know that will evolve. Will pull out the trichome scope after flowers build more and pistils start to turn. Temps are ranging 64 night and 82-84F day...may get some fall colors if I have any leaves left at that point. The taller buds are the LST mains on two that outperformed the others...so far. This grow will decide whether next is another auto or back to fem photos. Thanks for checking out my grow.
