first grow indoor and outdoor

So basicallt this is my first grow i started by getting 4 clones put 2 inside and 2 in a farm field of a friend. Anyways this is just general questions about out doors. First off i cant go check on these ladies at all (they are 40 miles from home) so basically im gonna make one trip out there in about 2 weeks. Should i take any special nutes for them or anything? Also what could an average yield be grown this way? Also when i go to harvest whats the best way to transport in stealth and not hurt the plants?

With out knowing how you planted them (what soil ,how big of a hole you gave them ) and where in the world you planted them , can't really give any advice or indication on yield ?

Well i got the clones in solo cups and just planted right in the corn rows. Im in michigan so i figured in about 3 maybe 4 weeks it should be starting to flower. Also i know the farmer just had the field treated with lime to bring the N back up. The strains are super lemon haze and mk ultra if that helps
