Week 4 already! We start to see a small nutrients deficiency, time to add some more organic stuff, i didn't applied too much so it seems it was food for 4 weeks, great as i dont want to give too much nutrients, I heard that organic nutrients gives a better taste and avoid salt accumulation in the roots, i always have been a typical grower using bottles but lets see, at the moment very happy, buds are looking good, i do need to add some sugars I think 🤔
