Amnesi-K Lemon - soil test / indoor

The week was uneventful. Her leaves are still looking great, she seems to have everything she needs. The amount of water she gets has about doubled. It's a bit hard to write about her size, since I'm bending the upper growth tips. But topping definitely has slowed her down a bit. I'm wondering weather I should top her again and when to change the light. For now, topping once is maybe enough; I don't want to wait too long for buds. Probably another week of growth before switching? Tips are welcome. Same day edit: I think I will find out how sturdy this plant is after all. While checking the plant in the evening, I noticed that I must have broken one of the two main twigs... The breach was already dried when I took a look. So in a desperate attempt, I made two fresh cuts, dipped them in some GBN Fast Start Gel and taped them together. Hope dies last, after all.
