Transplanted the plant, for me looks like a myth if you use a text pot you are braking the roots or so, because no stress here and maybe they grew even more than in a plastic one... In comparision to last grows i feel the plant prefer to expand in texpots, so from 15L and beyond seems logical to me to use a texpot.
Boosting the roots and adding some nutrients to the soil, Nitroguano, Top Vulcan and Micro VIta as i do in every transplant :) .
// Nitroguano, Top Vulcan and Micro VIta already on the soil //
// Watering 60-70% on the morning, and the rest at the evening when the sun goes down. If im rising the nutrient dose, first days im feeding plain water at the evening also //
