I have had issues since Veg and now in 5th week of flower, Leaves turning yellow with brown spots and slowing drying up and falling off. Growing in Fox Farm Ocean Forest and I did a start using Cal Mag half way into veg and no difference. I recently did a Flush and not sure if that has helped either the PH run off was around 5.3 and PPM as I started using Bloom A&B & Bloom PK Nutrients 3/4 way into Veg and still using. Any suggestions as this is my first indoor grow?
