Northern Lights Indoor grow

It's my first indoor grow and second grow in general. Every advice helps, thank you very much (:

Little Plant Update (:

Week 3 I just put them all into their new 5 liter Pots. I started with one because the repotting was very rough and I was scared it might be hurt to much, but the plant was fine and instantly kept growing. So I did the same with the other two.

Update start of Week 4. I think the Plants look really healthy. The Lamp was about 30cm over the plant for the last few days. I raised it to 40cm and turned the Power up from 50W to about 55W. I water them once the first few cm of soil feels dry. I don't let them overflow with water, i just get the soil wet. Water PH is about 7-8 Soil is Biobizz All mix 6,2 The water is pretty much room temperature. Right now I don't use any fertilizer, because the soil is fertilized for 2 Weeks. After this I will use Tomato fertilizer for veg-phase and a blooming fertilizer for blooming. (Both from the Hardware Store) Tomato fertilizer: NPK 3+1+4 Blooming fertilizer: NPK 3,5+6+6

Start of Week 5 I repotted them into the final 20 Liter Pots a few days ago and they grow so quickly and look very healthy. Very happy so far (:

Week 6 👄
