Are the leaf issue just on the plants with my nutes or on all plants?
How much of the micro nutrient did you give it? its only 0.1 mL Daily or 0.2 mL every other day. or 0.5 mL every 5 days. that may be not calcium or magnesium lockout that could be other micro nutrients and can be an lock out from PK but may also be an excess of micro. Hold off on the micro for at least a week if you have never seen this before and let's talk before putting it back in. This looks like an excess of micronutrients as our micro is very available so the small dose should not do this unless more was put in. Just want to make sure if it was from additon of my nutes to why its happening. thanks
Also as a note in general whenever you get a stress on your plant of any kind always remove the Enhance MC for at least 1-2 applications no matter if its because of spraying an IPM program, turning the lights on too quick and burning tops, or any other reason. We do this because regular Enhance MC is always making everything available to the plant so if you have a hard stress the plant will still keep uptaking as much as it can. By removing enhance mc for a couple of waterings it allows the plant to work on the stress rather than split its energy uptaking and working on the stress,
Also- though we talk about flushing at the end with Enhance MC but that is to pull everything out of the leaves, DO NOT try to flush the plant in the middle if there is a stress using Enhance MC as it will create more issues as it makes everything not available and makes the plant work harder.
