Northern lights auto 2nd attempt

All 3 girls are doing well. Scully got strong enough to be tied down but I noticed dark fungal growth on the top of the Coir. I sprayed it down with some light fungicide, left it a bit and flushed through with lightly nuted water. I think it's happened due to the lack of air movement and ventilation so I've cracked their door a bit and will be getting a small fan to keep them happy. I've not gone ahead with the fan just yet as I just can't afford it at the moment but there's been no resurgence of the mold/mildew since the topsoil was treated and the door's been cracked open. Already all 3 are much more vibrant and full than my first attempt and all are growing very well. I'm making sure to tie them down further if the main stem twists up too high and they've been much thirstier since the growth spurt. We'll be into flower next week, adding some PK to the nute mix so hopefully we wind up just a little bit fuller in the next few days for max bud sites.
