month and a half from seed

my month and a half old baby, its had a ruff life when germinated it was buried in soil and grown under and was saved and was actually the only one that made it heh! that was its first 4 days then it vegged for about 20-25days without nutes no checking ph etc it finnaly got hungry so my friend told me to get some 20-20-20 and thats been doing great! i just added the fan in yesterday cause my new setup style was heatstressing it. But tell me what u think how is it doing for its age, poor early life, still dont check ph , but its been loving the 20-20-20 thats when it packed on all its leafs u cant tell but i also attempted to "fim" it i dont think i got it correct but by the looks i got a good 4-5 nodes at the top. anyways pictures tell a thousand words "sept i cant get ta clear pic of the preflower but by eye it looks like a girl!!"

You shouldn't have to check PH if you have decent soil/soiless mix. Looks good and healthy so far. You'll know when it's too close your leaves will curl up and the edges will be burnt. You can place a temp gauge about the same place as the top of your plant to get an acurate messure of temp. I always have a few, one general one in the room, and one with the tops of the plants.
