VPD Matters. allot actually. you will discover this after the years.
as you can see from my setup i have made everything my self, never purchased any ready made product, i even do the lights, automation, watering automation my self, so everything must be optimised. and btw this plant is on auto pilot, i never check, only every 3 weeks to fill the water tanks.
your plants are okay, they grow with no issues, but maybe its the strain that can withstand such enviroment, i had some sensitive strains before and this made me make things perfect.
bro even for the soil, i make it my self, including all the food, amino acid Phosporus, NPK, i make all by my self.
this is how my fridge usually looks when things are done. here 350 grams trimmed dry buds, 3 strains. 13 weeks flowering, 150 Watts total light.
