Can anyone give me an answer as to why this one plants starting to get a yellow colour coming threw in the middle of the leaves? I don’t think it’s due to heat as the other plants are growing a nice green

Good afternoon My first grow on coconut substrate. The edges of the leaves have turned yellow. I give Kalmag at each watering 0.5 ml/l, maybe it’s not enough? Fertilizers Grow 0.9 ml/l Micro 0.6 ml/l Bloom 0.3 ml/l. Ph - 6.0 - 6.2. I noticed problems on the 17th day.

Leaves yellowing and burning mid flower
Air exchange, pH, nutes, and water should be good. Could my 230 watt on 100% be too much for her? Does she need more humidity? What causes crispy leaves?
