2 plants pictured look quite a bit different. so one may get done before the other. The first one has less plump and moer white pistils, i think. this one has longer.
You don't have to get the scope out yet... when it looks like bud you'd smoke, stat scoping trichomes.
if you haven't, drop N a bit as leaves in sencond pic are a bit glossy. prolly need to drop Mg a bit along with N assuming enough was given before.
