Sugar Black Rose Coco

At the beginning of the third week, the plant is still under only one module of the GC-4 lamp. (30 watts). The large amount of water was accepted quite well. However, the tips of the leaves are slightly burnt and curl a little. It was probably a bit too much fertiliser, I don't know the slightly pre-fertilised soil (Bio Bizz Coco Mix) very well. It is probably still a bit too cold or too windy.
