dont be a douche on this one but ive got 2 leaves that are regualer weedy leaves that are directly across from eachother and the other set are rounded leaves, whats up with that???
Not to be a dick, but, it sounds like you skipped over alot of stuff, especially the seedling stage. Start from the beginning, and research every detail, as they grow. If you read as your plants grow, that'll give you plenty of time to keep your reading on pace with the plant's growth. If you would've started with germination/seedlings, you'd have read/seen many times, that those round leaves are what you should be looking for, as soon as your plant pokes out of the soil. Trust me, take your time reading, it'll be worth it in the end.
