Hey guy, nice to see them poppin' up. First thing i noticed, you should definitely put them into smaller pots. I don't know if i'd go dixie cup small, but thats what i usually start in. the plants grow better when the pot fits their size, and when they get too big for it, transplant to somthing a bit bigger. i'm not sure on the exact number, but you should transplant like 3-4 times during a grow...you'd better look that up though lol. and i wouldn't worry about pH at the moment, i've been growing my plants for a few months now without knowing. i'm not saying ignore it at all, i'm stupid for ignoring mine, but right now that jiffy mix should be right fine for those seedlings. if you do decide to put em into a solo-cup or somthing, remember to poke holes in the bottom for drainage. you might need more light too...i'm running like 14 cfl's on my 2 plants. you may not need em now, but definitely when they start getting bigger. sorry i can't be more help, i'm pretty new to growing myself, still on the first and just starting my new clones in flower for a SOG, but if you have any questions i'll try my hardest to help you out, as will the rest of the community here! keep on keepin on guy.
