This is my second grow and all the ladies are doing well except one. I originally assumed that I was over watering, but the soil (FFOF) is dry inches down and the last watering was 4 days ago. No added nutes, but I use 1 tsp molasses and 15 ml of Rhizotonic per gallon. They are in week 5 and are from Bruce Banner 2.0 feminized seeds. Most of the rest have 4 good nodes. The first picture is of my troubled girl, and the others are from other plants in the same batch. Should I flush it? Under watered? Thank you in advance.
