I have decided to remove the air pump and stones as they are extremely noisy. Instead, I decided to use my recirculating pump as a dripper to create tiny bubbles sufficient to provide oxygen. It has been this way for 5 days with no ill effect yet and the girl looks awesome. She has begun sexing but no sign of preflowering yet so I'd say this is also a veg week but it does look like flowering will begin for the next week in a few days. LST seems to have worked well, however, I cannot help but feel maybe I stunted her growth by begining so early. Lesson learnt. As flowering has yet to begin, the res change will be delayed by a week or two until nute change is required after which, no further changes will be carried out.
