When to start feeding Autos in soil 5GAL root organics

First and foremost thing to check with any deficiency is if soil ph is in range. As plant grows and what it requires changes, when we add additional chemicals, organic or not they can alter ph. Especially if there is not proper run off. One appears to be magnesium deficiency while another pic shows potassium deficiency. I would start there then adjust appropriately. Good luck and happy growing. 🌲🌲🌲👊

I have no familiarity with your nutrient regimen. BUT, what you're seeing is definitely an early stage calcium deficiency and easily rectified with a calmag supplement. In DWC 1ml/L will do it and you should see it clear up in about a week. Botanicare Calmag + and CaliMagic by GH are the standard but any other will do. Not a big deal when you're still in veg. In corporate it any time and you can cut it off 2-3 weeks from chop without realizing any disadvantage. Good luck with your grow!
