So here are the things id like to tell: - they are healthy - all are females (super lucky?) - they are growing faster - idk why but a few leaves are getting dried edges, very thin but its there, you can see it in the picture - a mini plant had 2 sets of yellow dead leaves… like the lowest of 2 leaves. should i be worried ? Is it telling me about a particular deficiency
