I forgot to ph my water twice for my autoflowers. The ph was 7.3. The leaves are light green and the flowers stop growing. I'm in week 6. Should I flush?

Kinda maybe not really… need some more info/visuals. If you’re using coco, I’ve read you may need to flush salts out occasionally.

I'm at a stage of learning and find too low RH looks like a lack of nutrients, IE yellow leaves and brown spotting with bleaching.
53% is where I would have mine at your stage. Temps at 80 to 85 deg.

If you’re in soil ph’ing your 7.3 ph water is pointless anyway.

How is it pointless?

I can agree it’s pointless to a degree, the OP is concerned/learning about watering their plants in soil with something that has the ph of good tap water. (Sorry to be blunt to the OP). But they learning bro.

But is it really pointless knowing/monitoring/improving water ph in any grow media?
