Dark Green Leaves and Purple Stems
Sea_Weaselstarted grow question 2y ago
Plant B has had no nutes its entire life in FFHF soil (3 weeks). Stems are a purplish color and starting to droop a little. Water is always pH'd around 6.3 but I haven't tested the runoff yet. Phosphorus deficiency? Heat Stress? Watering conflict? NL Photo just started flowering.

Leaf stem being purple is ok .. your branches are what you wanna watch out for purple..your branches are green so all good there...looks like too much nitrogen which is why your leaves are dark green .. less nitrogen as you enter into flower .. she looks good aside from the nitrogen.. now she will want more phosphorus and potassium
