Started adding more bloom to the mix and normalize the nutrients again. Plants aren't showing any issues on the top layer. but have a few dying leaves in the bottom due to little light from the bushy canopy.
Did a minor trim of leaves to prevent mould even knowing that this might stun the plants, wasn't worth the chance.
I'm fully aware now that 2 plants is waay too much for this setup, next grow will be 1 plant in a 20l pot instead.
I changed light schedule some so the plants get more time to heal.
Water consumption has gone up alot, and i almost have to water every day.
