Help with new NFT system

Hello,
I'm looking for advice on my aeroponics system. I added a second LED grow light (the bright pinkish kind) about 2 weeks ago. The idea was to have a more even distribution of light across the plants. The growth exploded but about a week ago the tips of leaves started to wilt and now some are burnt/browning/and some leaves are yellowing. the larger plants are a 6+ weeks old The roots are growing very well and look good I've read this can be due to a mineral deficiency and that the solution could be raising the lights (I've done this) and adding a fan to increase airflow and transpiration.
The new starts also show darkening of the leaves. This is butter bib lettuce so I expect a bright green color. Thanks for any advice!
