Can you take a pic without it under the light. Hard to see detail or color...

heres some pics in light and under iphone flash im hoping the yellowing is due to needing nutes as only just come off plant start

Dude ph for soil at 5.6 not good.. They look lil bit over water how often do u water!!

How far away are your lights & what air flow you got, look heat stressed to me. Plus ready to be transplanted to bigger pot.

She is pretty dark, might it be too much N? If that is soil, you want to water/feed around 6.5.
