I noticed this growth on some mid and lower l leaves. Seemingly happened overnight. Only seems to be happening on one of three plants. This plant had very strange looking leaves right from the start. The cotyledons were purple on the edges. I am growing in Fox Farm ocean Forest and it is the start of week 4. Strawberry Cheesecake Autos from Seedsman. pH of runoff was 5.7 on all 3 plants but the ppm was almost 5000 on this lady and just over 3000 on the others. Growing under and 18/6 cycle with an ionboard 4400. Thanks for any suggestions. Peace
