Partial reset on this girl who is obviously stunted and struggling. Not all strains are created equal and experience combined with skill goes a long way. So, taking my lumps with this girl. So, long story short, I reduced the ppm by draining and replacing 2.5 gallons of ph'd RO w/cal-mag added. This resulted in bringing down the ppm to roughly 500 w/ph at around 5.6. Will continue to monitor ph, ppm, and water levels for the remainder of this week looking for stabilization. At that point, I will gradually raise the ppm levels. If she doesn't make it back before TKO is ready to flip, I may need to scrap her given limited space. Come on girl, let's go... Midweek 4 update: Well, time has come for a decision. I moved the PBCRbx over to the 3x3 grow tent, so I can continue to care for her. Clear case of too much nutrients (high ppm levels) that have stunted early stage veg growth. Tried monitoring and adjusting ph twice a day but ppm remained higher than range resulting in fan leave tips looking burnt. Also some nutrient lock out occurring. Given ppm remaining high and water level dropping, I decided it was time to do a complete flush. Emptied and thoroughly cleaned bucket, air stone, and air line exposed in bucket. RO water with cal-mag and nutrients ph'd to 5.5 w/ppms at roughly 625. A day after flushing, the PBCRbx is looking a lot better. As a back up, I am running a separate PBCRbx by Ethos in a 3 gal fabric of coco peat, which is doing very well.
