Yellowing fan leaves during flower

Hey grow fam, ive got a lemon haze auto in week 4 of flower, i removed probably 12 yellowing fan leaves about a week ago and another 10 or so today, i was out of town for a few days and she was definitely thirsty when i got home. Is this normal during this stage of flower or do i have an issue?

The drought is likely your culprit. She sacrificed them to nurish herself.

At 2k ppm, and your pH is coming out a little lower than going in, with yellowing leaves, I’m gonna go with the extended drought. Your numbers aren’t really out of whack, but you may have a dry pocket in the soil. Maybe a thorough soak with pH’ed water to get your ppm’s closer to 1000. Then get back on your feeding/watering schedule at full strength since you’re in full on flower.
