if your growin in quality soil, that should be enough for the first month
then go lightly, i use a quarter of the recomended strength then gradually increase that each feed till im givin half strength
by then its HARVEST TIME
i use bio harvest grow & bloom
and mainly grow lowryder 2
as long as your using a decent compost/soil you will be fine with that
the soil provides plenty for the first 3 or 4 weeks
then go light with the nutes or you'll burn 'em
I introduced Botanicare Grow nutes at half strength 4 days after breaking soil. Full strength 2 weeks in, and haven't experienced nute burn at all but my soil is nute-less. Of the 8 germed in a baggie (100% germ ratio) seven broke soil. 4 females, 2 males, 1 is locked up or something(slow growing)I'm 24 days in! My first LR grow as well! They are LRx1 from Dr.Chonic.
