Hello. I put my 3 indicas and 1 sativa into flower mode on 11/5/19. Without knowing, I let them go for 6 weeks in the low to mid 60's during the day and low 50's at night. They had slow growth for these 6 weeks. Finally corrected the temps to 80 degrees day 68-70 at night. Now at week 8. They are sprouting new white hairs on top of the orange hairs. My question I guess is, how do I determine how much longer that have now that the temps are corrected and now have new growth. My sativa fan leaves are yellowing even with feeding but buds have new white pistols sprouting? Any suggestions?
The new white pistils is normal. Most strains will do that 2 or 3 times before are ready for harvest. From looks of buds, you still have a few weeks. They should swell much more in the last 2.
