A Question

My plants are a month old from seeds, i started putting liquid karma in there water about 1 week ago and i was wondering when i will need to start adding fert and what would be a good product to use any input would be greatly appriciated.

also how old are they when i should make the first clone for finding the sex.

anyone have any input??

What soil did you use? I always use miracle grow moisture control so I add no nutes for 30 days at least unless Im going to flower then I add high phosphorous Indonesian Bat guano and sugar daddy at watering.I take clones to early sex at about 6 nodes of age from the seed plant
