Nice that means its from the same batch as my Whie Rhino, and the 2 me and buster planted turned out female so fingers crossed for you m8. If you cat goes outside it could pick up a few bugs, and it only takes a few bugs unchecked and eventually u will be infested, I think i have almost killed all the fungus gnats i had but it taken a while because they can repopulate fast.
As for the plant i think its nutes but i am not sure i would wait for some 1 who had done a few more grows before u decide what 2 buy.
This is a good page for leaf probs i found in a post somewhere.
