Sorry to hear you're not happy with the overall results, but it's all a learning curve bro. You could try giving black strap molasses to the remaining ones see if they plump up a little for you. Hard to say what went wrong, your pictures looked great? Is it maybe a lighting issue? Maybe you need something a little heavier for when they hit flower? Some bat guano 1-10-1 and something with some Potash, Sulphate of Potash is water soluble and fast acting.
