Critical orange punch (soil grow)

Soo first day of 12/12 today, plants are doing really well.. I have fed them once with a solution that a friend has made as the leaves were starting to turn yellow and I assumed this was lack of nutrients as I've not fed anything other than what was in the soil to begin with. and they seem to have liked it!! I feed them water every night I pour it straight into the pot suacer instead of the soil.. I have added an extra light but the flower mode has broken on it so might have to be replaced.. I have also added an dehumidifier that also has a carbon filter inside! So that has come in handy.
