First time grow Brazil Amazonia LED

Still the same conditions like in week 2. The plants height did not increase that much yet. I hope its not a bad thing.😬 The plants seem to be healthy so far. I'm planing to buy a hygrometer Day 17: 4 Nodes are showing so far. I don't know if I should top the 5th node or wait for the 6th. I'm not going to FIM since I only read negative stuff about it (long recovery time). The roots are also not showing yet on the sides or maybe I'm blind. I'm also not sure if I should put them directly in the 11l pot or 3.8l pot but probably I will go for the 11l :) Day 18: Changed the pot to 3.8l root pouch with prefertilized soil: Biobizz All Mix. Should be good for the next three weeks Day 21: Topped them above 2nd node. I'm trying to get 4 colas each plant ("uncle bens topping"). Since I didn't want to waste anything I'm also trying to clone the toppings.
