Shes in a 5 gallon bucket
...hopefully with plenty of drain holes in the bottom.
I'm going to "pitch" the old wet/dry cycle of watering, but with a small wrinkle.
You didn't describe your soil, so IDK if it was amended or has some time release fert's in it, but IMO, what you gave here is woefully inadequate. I also believe, giving any plant in 5 gal of soil, 1 liter of water at a time, results in improper watering. I don't let plants in bloom go
completely dry, but most soil grows should be able to take at least 4 liters (6?) at one time. As the pot dries out, the plant sends roots out looking for water and food. It is the only form of exercise they get and plants need that exercise to develop a strong root system. When in veg, I let them get to the point the just begin to wilt. Within a couple of minutes after feeding them, they are perky and happy with a good growth spurt.
I don't use Flor+, but my understanding is, it is an additive/enhancer, NOT a primary nutrient source. I'd go to the GH feeding schedule and follow it, but at 1/2 their recommended amounts to start.
