Well I learnt a bit this week. Some of my plants leaves had been yellowing from the week earlier. I was sure my watering habits were on point (roughly every 2 1/2 days). I came across a sub-reddit discussion about wind burn and the penny suddenly dropped. The pedestal fan I have in the tent had been blasting directly onto the poor girls. Lesson learned! Have turned it around so it is facing the wall directly. Many of the leaves have died and dropped off. I helped a few and am now back on track!! Happy growing 💗
