For this grow I litterally did not have to do anything. The plants were only watered when it hadnt rained for 2 weeks.
Except for that I did not have to do anything.
The soil was likely rich of nutrients, as I did not see the plants suffer any defficiencies.
At the end of these few weeks, some flowers started to turn beautifull purple and orange.
At this point I did not even want to feed them, to keep it a full Bio grow:)
