Slow veg growth

Hi Martian_D, first of all, I noticed you already put some top-max from biobizz and that's an error. Top-max is for the flowering time. On the nutrients schedule from Biobizz, flowering time starts at week 3 but it actually just means first week of flowering. You wrote you grow soilless, it looks to me you are using soil no ? if yes, please write what soil you use please. My first though for the way your plant looks like is overwatering, it overall doesn't look healthy and the leaves are "droppy". According to you, they get 1.3 litres of water a day! With the current size of your plant, she definitely can't drink that all. It's a common mistake to overwater at the beginning (I did it too 😉). How often do you water the plant and how much each time?
