Nutrient issue. Possible early calmeg deficiency


Gorilla glue #4, 3 weeks into bloom. Recent trimmed. Water temp: 67, PPM: 924, pH: 6.6

I'm guessing early calmeg deficient, what do you think?

    She looks nute burned.

    Above a pH of 6.5, Phosphorus and zinc begin to get locked out. You may also see calcium issues.

    Drop ppm’s to 500 in case of lockout. drop pH to 5.8. If you havn’t replaced reservoir since flipping to flower, would be worth doing a reset.
