High Dutchhobby,
Did you add some pk 13/14 already???
I would just add a little!
20% from advices amount on the bottle and up this with 5% ever week till you reached 50%. This is enough till harvest and you should almost be done by then. The last 2 weeks can start flushing.
When you have any other questions you can always send me a private message!
Happy Growing! 😋
