Very hard grow this time ... Canna bio terra plus and green buzz nutrition are hard compared to biobizz , biobizz everything goes well and fast , I try and try and try to get it better and understand what's wrong
I think that I underwatered them :/ I will trying to watering them more and more often
Edit 1 day after the problem was underwatering !
to me it looks more like a lightburn
are your lights running on 100 percent? in that distance? if yes... less is more
and plants look thirsty too
good watering routines make your life much easier
@GreenBuzzNutrients, it's too much nutrients (3week of calendar) i watered them with only 1/2 and they like it , light is at 35% actually , canna soil is different than biobizz than I used I'm not familiar with but it's ok i learn very fast 😈
