hi there finally got me grow set up I brought 40 clones from a friend of a friend.I know it is a sativa b/c of the leaves.
The guy said they flower in 90 days I researched it I think they are light of jah. Anyway I planted them 3 days ago and been spray them but only 18 of them were rooted the rest died.So here's my question
Can I get at least 4.5 oz off each plant here's my set up let me know what u think thanks

3 1,000 watt lights-18 plants
4 gallon pots
Vegging for 3 weeks
Clones are 4" tall
FF ocean soil
FF grow big/big bloom/tiger bloom nuts

You have a lot of light, but asking for 4.5 oz per plant on your first go is REALLY optimistic. Especially not knowing the full potential of what you are growing. If I were you I would shoot for 2 oz per plant and call the rest "icing on the cake".

most sativa's grow dramaticly less indoors, they are ment to be an outdoor or green house plant for the most part, 4.5 per plant is pushing it a lot, like oks226 said 2 oz per plant would be nice
