I just started my second batch of seedlings, and for some reason they just arent growing like my first ones did, and i have no clue what i could be doing differently. Im using bag seeds from 3 different bags, 4 20 watt plant fluoros about 1/2" away from the plants, and and good soil, half with miracle grow soil and half with no name soil (im experimenting) they grew like 2" tall, got the second set of leaves started, then just kinda stalled out for no reason.. any ideas? FYI its been 1-2 weeks of growing now depending on which ones were planted when
