whats wrong with my leaves?

ok well theres there spots on my leaves and idk why can anyone help me... also can u tell if my plants are male or female yet?

It's nothing and you can't tell what sex they are. Males signs usually show within the first week or so of the flowering period were the lighting it switch to 12/12... preflowers are tiny indications of the sex of the plant in the late stages of vegatative growth... its not 100%.. they are hard to find and sometimes you will need a microscope to see them. Hope this helps you out a little bit...

ok thanks... so how much longer do you think i got till my plants start flowering? cause this is my first grow ive been smokin for a couple of years and tried it before, but this time i was seirous about growing so

Look around your plants for any type of bugs. Look all under the leaves and at the nodes.
