Hi
@JERgarden ,There doesn't seem to be much nitrogen excess. at this stage of flowering the leaves would already be burned with excess nitrogen. it may be the beginning of calcium deficiency, the first symptom is the leaves turning dark green before the spots appear. In general between 4-6 weeks the EC should be approximately 1.5-1.6, between 6-7 weeks of flowering the EC should be 1.7-1.8 but this is just a general idea, each plant has its own feeding rate. I would give them a bloom booster for fattening together with the bloom you are giving, organic molasses is a great choice. good luck in flowering 💪👍
