In Need of Info First Time Grower

Hello i dunno if many of you have seen my other posts, but i am new to growing so what i started was is bagseeds. here is my pics i need some stuff answered tho.



i call this my frankenstien plant, it was my very first grow and if some of you go to the weed journal youll see my post this is the one that my dog tipped over, i call it frankenstien b/c some of the leaves look quite odd. i was going to get rid of it, but you know its my first plant so it was kinda sentimental




Heres another one that i panted 2 weeks after the frankenstien one can someone plz tell me why is one of the leaves looking a little nasty, wut i mean by that it that its like shriviling and its getting kinda darker then the others.



this is my last one it was planted 2 weeks ago


the frankenstien one is in a 6inch wide and 12inch down pot, the others are in a 6inch wide and 7inchlow pot. should i move them to bigger pots?

also when can i start to move to 12/12 so i can see there sex, right now there under 18/6

also i bought foxfarm big bloom and grow big, when can i start using the grow big? its also in miracle grow potting soil

plz im very new to this so if i do something wrong dont flame me about it, thx

i would use the foxfarm grow big. just dont over do the fert. cuase it could burn your leaves. let your plants get a lil bigger then put in a bigger pot. i use 3 gallon pots. i wouldnt use the miracle grow soil anymore. because i think they have that time release fert crap that could mess your plant up.

k thx, can someone tell me wuts wrong with one of the leaves in my plant?

Do you mean that leaf on the left that is curling? Don't worry about it yet. Get your plant on a good schedule first. What cricket posted is very good advice.https://www.rollitup.org/../members/crickitmd.html
