Ok you have an autoflower.
Feed LIGHTLY and include a LOW N calmag product in feeding.
I don't see a watering problem, but remember to water when soil feels dry to the touch below the surface and as the girl grows - dry down to about 1 inch before watering.
NO Ph problem! On that note, Soil will self adjust Ph to 6.5 to 6.8. unless the Ph of the water is below 5. or over 8.
Most quality nutes are Ph neutral.
KEEP IT!
