Thanks she's had hours of training already. Think it's new grower anxiety. Always learning, made mistakes and hopefully I don't repeat them. I think once top sites start forming I'll be at ease I'll try post some photos of top sites and I can monitor growth easier that way too. I'm using a transitional nute system as mentioned, I'm using 2.5ml terra grow and 2.5ml terra bloom per 2l until she stops growing upwards I suppose? Thanks for the comments
