My 1st Grow / Pineapple Express

pineapple this week is not grow as I expected. It is as if one day he decided to stop his fast growth, since he was one of the best fit from the beginning. Could this be a problem with the guardian I put on her? I have perhaps touched a root planting it .. I hope not, let's see how it goes next week, in any case now it is the smallest of all. Good week and good growth to all of you 👊
