yellow curling bottom leaves - help!

[BBD32]

OK so this is my first attempt at growing and I've ran into many problems. First the humidity was way too low then I found out I was watering with 8.1ph. Now they have yellow leaves, some of which are curling. Any ideas?

I flushed the plants with balanced water 3 days ago, haven't watered since and there not getting any better. All from seed and 23 days old.

Pro mix
T5 6500 4 bulb
73-85°
40-50rh
6" pots

My buddies run Pro-mix at 6.8pH, just keep giving nutrient solution at 6.5 - 6.8pH...sounds like the problem was from a high pH and it was locking out certain elements....you have to remember that nutrients are the lock & pH is the key to unlock the elements to the plants roots, pH is very, very important in any grow medium.

Also, pictures help us diagnose much better.

I was hoping that the pH was my only problem at this point but with the leaves not getting any color back I wasn't sure. So the high pH could have caused most my issues you think?

The affected leaves won't regenerate back to their nice green selves. Once they have been damaged, they are damaged for life.
Keep a close eye on all new growth. If the new growth is healthy, then you have no worries.
