1 def looks male, 2 might be too, but 3 and 4 look like they may be girls... so if you only have one plant it may be a hermie...that my friend is a male... judging by the first pic
sorry to inform u
you can if you want too... but like someone else said hermies tend to produce more female seeds than males... at least that is what i have heard too... but yes i believe it can ruin your crop if you have more if it is a hermie that is... it still has pollen sacks...can u smoke a hemie? will it ruin the rest of my crop? all 4 pics are just one plant
