You’re thinking too much, clipping too much and watering too much. Stop trying so hard.
Why the distilled water? Unless your tap water is completely out of whack, it’s likely better for your plants. Water until runoff and wait until the pots are light before watering again. Watering every day is a big no-no. You’re either drowning them or not getting enough moisture to the bottom of the pots. Plants need a proper wet/dry cycle and I can guarantee this is one of your biggest issues. Same applies to feeding…less is more.
Last pic of leaf looks like one of 3 things.
1. Leaf miner damage
2. Overwatering
3. Possible Mg deficiency
Just keep an eye and see what happens. Don’t overreact.
