Hello ytOracle, Ok the problem here is not enough blooming nutrients. Only 1 ml grow and 1 ml bloom os simply not enough. You want al least 1 ml grow, 3 ml bloom and 3 ml top max and a cal-mag supplement to prevent deficiencies like this. You also want to measure the pH from the water. It should be around pH 6.5 in able for the plant to take up nutrients from the soil. And when you water then you need to water till 20% runoff. To prevent nutrients salts building up inside the soil. This will cause the EC and pH to raise and will cause deficiencies because the plant will not be able to take up nutrients. I hope this helps buddy! Happy Growing! 💚
