The plant still looks pretty ok :).
I would like to see some growth in the following days, so I can start with the LST asap and the plant would still have some time to get bushy before the flowering starts.
The spots from the last week are still there, but it seems there are no new problems appearing.
I will probably stick with just power root nutes for the royalmix until the first weeks of the flowering.
Day 17 update:
She reached 10cm in height, so I started with the LST. Hope I managed not to stress her too much :).
