I’m on week 6 of flower on my first grow in Fox Farm Ocean Forest soil. I am using Fox Farm nutrients as well at half strength. I suspected my plant might be nutrient locked because it’s showing signs of calcium deficiency but also has slightly burnt tips. Other than slightly burnt tips and mild calcium deficiency, it looks healthy and the buds are developing well. To confirm my suspicions, I gave it plain PH balanced water measured at ~200 PPM and the runoff measured at ~900 PPM so I’m pretty sure it’s safe to say that there is a build up of nutrients in the soil. My question is how do I fix this issue so late into flower? Should I continue feeding plain water until the PPM of runoff more closely matches the feeding water? Or should I flush the next time I water until the PPM is lower, then continue feeding on subsequent waterings?
