Today is day 40 of flower. I noticed a couple days ago there was a leaf or two beginning to yellow. Today there’s a lot more leaves that have just the tip yellowed and a couple leaves have died off. This strain is supposed to flower in 60-65 days. Just curious if it’s normal yellowing due to the flowering process or if I have a problem? I quit administering nutrients this week since it’s only got 3-4 more weeks until harvest.
