hi i'm a first grower please help me :-P my plants must have some kind of nutrient problem as you can see in the photos it's bottom leaves are turning black/brown they are tropical sativas(i think) i keep them in a 12/12 photoperiod, water them with rain water (around 6.5-7.0 ph) and give them a 14-14-14 slow release fertilizer mixed with an 11-23-11 because it looks like they have a phosphorus deficiency but it's not working. any ideas??

lol this is too funny, you're growing in mud/clay in decorative pots. give grandma her pots back, sonny
 
i agree with u KT420, the only advice i can give u being kinda a noob myself is RESEARCH!!!!!!!!! before u start to grow get a basic understanding of what you are trying to achieve, and then if your still needing some help ask away. personally what ever your using for a medium id change oh and your plant wont need any nutes till week 3/4 as they dnt need alot to begin with if you using soil as most come with nutes to last for a while. good luck with your grow anyway
 
haha i know i'm a total noob i found the "clay" in my back garden actually it's soil... what could i use then? would that fix my plant's problems?
 
that's not soil buddy.....that looks like the red clay from a hut in a dwelling somewhere in mexico. go buy some potting soil WITHOUT time released nutrients.
 
i personally use a good potting soil with 1part perlite and 1 part vermiculite, i wouldn't use soil from your garden as it can be full of shit that you dnt want. you say that u think that you plant is sativa, well for your first grow that could be a challenge for you but dont give up ive found this hobby to be fantastic, my first grow was uk blue cheese really dank bud took 10week to bud the best smoke ive ever had . but it would be good to see hw yours pan out. keep me updated m8 peace
