Day 22: after yesterday's watering, the plant seems to have recovered well, although she bears the marks of my inexperience.
Day 25: watered with 1.5 l water + Plagron Alga Grow + Plant Succes Orca.
Day 27: showered the plant with a mixture of distilled water, neem oil and soft potassium soap.
Cold and rainy week, unfortunately. The plant is doing very well, especially since I gave her fertiliser along with the water. That girl makes me proud.
@CanuckTaughtMe,
thanks for the vote of confidence, but I don't think I'm a good example: it's the first time I've reached the fourth week of cultivation and I'm making a lot of mistakes...
