These sunflowers are on my window ledge getting ca 8h of sunlight per day. When they lack water the leaves start hanging dramatically. 30 minutes after watering they correct themselves. Plants look pretty healthy all around to me except for the yellow leaves. I get these on EVERY sunflower I have.
I water them thoroughly as soon as the top 3cm dried up which is around once every 4-5 days. Pots are properly drained.
