AsNoriuanswered grow question 3 years ago Wrong pH or too cold temps, will start calcium's issues soon.
Never drown roots !
Let her dry out !
While she does so, but pH meter or strips. If you buy strips, search for better quality by rewies on Amazon and smaller distance, like 5.5-7.5 max, ussually they are for aquariums.
She looks hungry, but till she don't start to uptake water fast - do not feed get anything else than light Cal mag, like 0.5 ml / l . Then she will be very hungry for PK and a bit still for nitrogen.
All the Best !!!
