Pistils have started stacking up. Cutting nitrogen low this week. I think I may have overfed it. Runoff ppm was high.
Day 37: fed half the amount of nutrients
Day 40: Showing cal/mag deficiency despite 0.5ml/L dosage. Will increase dose in next watering.
Day 42: Cal/Mag deficiency seen on leaves. Given extra cal-mag at pH 6.6. Runoff pH was 6.9. Maybe pH is the problem?
