For this run, I decided to let the plant do its thing. The last few times around this time, I often grabbed the scissors and removed a few large fan leaves. Let’s see how long I can hold out.. 
One positive thing I’ve already noticed is that the side shoots are naturally growing a bit wider, and so far I haven’t had to help with LST.
Also, the stretch has begun; the plant is making a good push every day and now has a height of 23 cm. DLI at 30 and PPFD 450.
On 10.09., 2 liters of nutrient solution were watered, it was the first time for Plagron Alga Bloom and the last time for Power Roots. There was also EM Aktiv.
Plagron Alga Grow 2ml/L
Plagron Alga Grow 1ml/L
Plagron Power Roots 1ml/L
EM Aktiv 10ml/L
In addition, I measured the pH of the nutrient solution once after adding fertilizer to check, it was at 6.58. 

I’m very satisfied, curious to see how it continues..
Happy growing everyone
