I see a potassium deficiency. What else are you seeing?Your plants are showing multiple deficiencies.
They are Black Lime Reserve being grown in Hydroponic soil, I water them every 3 or 4 days with Ph balanced water and every other watering I’m adding a tiger bloom by fox farms
What is your room temp?This is my grow rn. I can tell something is wrong but I don't know where to start. Is it temperature? I live in a cold place but I've never had problems before
