m0useanswered grow question 3 months ago looks to be a bit of burn from over fertilization. nothing to worry about your not smoking the leaves your smoking the buds.
Also the frosty crystally bits on the sugar leaves are the trichomes. The bits you want. They call em suagr leaves cuz it looks like they have grains of sugar on em. same with the buds.
