I have 5 plants but the attachment upload on here is so slow and only allows individual photos so I have only attached 2 plants 4 photos.

Try reducing your file sizes

I would try to get the ph down to 6.5. What’s the ppm of the runoff?

Don’t worry about the odd first set of leaf as long as there not browning and falling off most of them are just a genetic deform but the others look great. When was your last watering? Soak them after they dry out and water when they get dry and light. They like extreme wet to dry conditions and not kept wet all the time.

Add calmag atleast 3ML to 1 gallon if not more.

Don't worry about runoff ppm in soil. If you're collecting enough runoff to test, you're over watering!
My water is 7.2 well water and never had any problems with the ph in SOIL.
Soil watering rule of thumb, 1 quart of water per gallon of pot size. Wait till pot is light, then water again. Don't go by how many days go by.
I use 600w led (actual 250w I think) I keep my lights at 32" to 34" above the plants. LED can burn the plant if too close even though it seems cool in temp.

Agreed, they look fine.
