Hey Pros, All girls are from the same mother and ...

By no means are the bleached. This is a different animal as when they get bleached you’ll get curl said the plants are attempting to get away from the light immediately and see damage on the tips almost as quick. However lights in the center under the light receive a higher amount of lux/umol and therefore they generally use more potassium, phosphate, calcium and magnesium. This is especially true in high intensity led lights but not limited to any high energy source. As a wiseman once told me you almost never hear of a Calmag toxicity. So in my garden when the lights are full strength I add 30% extra calmag and 20% potassium and phosphate and have never had a problem other than that still not being enough under the HLG’s. Ps. Your plants look perfect.
