Progressive yellowing on older fan leaves ~F14-F35Hi, past two weeks or so I've been noticing progressive chlorosis and eventually some necrosis starting from the edges of the leaves and working inwards.
Photos of this can be found in Week 18 Flower denoted by "For grow question #x 12/1"

Why is this seedling so weird?Weird seedling leaves.
I'm pretty sure environment is OK as the other 3 are looking OK.
Temperature Day is about 78F and night about 68F. Humidity between 55-60%.
I've been careful to not overwater, but I'm no expert.
Maybe just funky genetics? Any other ideas?Leaves. Twisted

Перелив? Кто думает, что кокос невозможно залить посмотрите на это!Полив 1,5-2,5л через день, дренаж в среднем 0,5л, контейнеры Bagpot. Считаю, что с циркуляцией всё в попядке, так как влажность упала до 35% при 25° (свет ~1000W) и при том, что на улице влажность 50°, т.е. парилки нет. Обдув вентилятор 15W.5y ago

Discoloration On Lower LeavesDiscoloration on some lower leaves. Rest of plant is healthy, so I'm wondering if I should top dress with my bloom nutes now?
