Critical photos in DIY organic supersoil

I'm lowering the watering a bit because RH raises easily to 75% if left unchecked and my dehumidifier struggles to work for long periods without raising the temp to >33c. I also decided to supplement the water feed a little with potassium as the only source I have in dry amendments is Guano and I don't want to burn my plants but I want the nugs to fill in nicely. I'm using Madame Grow Bazooka Bloom which is fully organic, and went with a low dose for now. I may increase it if I see the buds don't fill as nicely as I would like. The goal of this grow was to test the supersoil without feeding anything more than water, but I will prioritize healthy plants and a decent harvest over rigorous testing 👽 End of week update: I topdressed the pots and gave extra nitrogen to the plant in the back left. Topdressing: - blood & bone meal (only for the back left plant) 2 scoops - kelp meal 1 scoop - biochar 2 scoops - humic acid 1 scoop - diatomaceous earth 2 scoops I've also ramped up potassium in the watering, currently at 3mL/L.
