Hi there to everyone at thc farmer, Im a first timer and i just wanted to know if im on the right track with my first grow.
Ive recently germinated some seeds and i have planted them in a pots containing
1/4 perlite
1/4 vermiculite
1/4 peat moss
1/4 premium potting mix

1.Is this soil medium seem ok

2.Ive started feeding them canna veg A & B nutrients 1/3 strenght, but do i have to add anything else to the water apart from ph stuff. ( I know that the nutrients are for hydro but i was told they can be used for soil as well.
P.S the plants are 3 weeks old, under a 600w hps light.

Any help would be appreciated.....Thanks

at 3 weeks old and in premium potting mix to boot, i would'nt feed anything but water until the fifth week. If u have a slow release pottingmix it will just piss of mary evenmore if you keep adding nutes. find out how long your soil will feed on it own and then start off slowly after the potting soil wears off. Slow win the race. good luck

Everything seems fine to me, after all only a quarter of your medium is premium potting mix, if your plants start to show any signs of over fertilization then ease off the fert.
