Mg soil........phhhhhhhh
possible overnute and/or undernute due to ph lockout.
check both water and soil ph....both should be between 6.2-6.8.

just some basic info to clue you in..... good luck.

wow she looks way too young to be fertilizing!!
you shoudl totally check the pH of your soil also like weedhound recommended.
also make sure light isnt too close its still a baby =)

good luck

Pic of whole plant?
Yellow low leaves do NOT necessarily mean the plant is sick.
What is your water source? The only thing that looks liek to me is too little light or too little calcium.

Hey Stinky thanks for stopping by.

The last picture is a picture of the full plant.

You can see its progress in my grow log.

Im using tap water ATM that I havent been ph adjusting though i have a probe and ph adjusters to do so. Im using a 400w hps light I doubt that is to little light.

Ill check the run off ph today. If the ph of the soil is to high how would i go about fixing this?

first off...stop the extra nutes... MG soil has enough already. second... make sure your not overwatering.

ding ding ding.

This is my vote also. In a later post you acknowledged that you aren't measuring the ph of your water. It's very easy to end up outside the range you want to be in. Always, always, always check the PH of your solution before you feed your plants.

And check the run off PH of your medium periodically. I like to check mine once every 2-3 weeks and immediatley after a transplant so I can be sure of what PH my medium is resting at when it's new.

:hippy:

Other than that your plants don't really look that sick at all. I bet it flares up soon though.

[stinkyattic]

Yeah. Impending flare-up. I JUST looked at the last pic and it looks locked out. You're going to want to do a good flush at pH 6.8 and then feed immediately with 1/2 strength cannabis specific grow fert, preferably an organic one like Pure Blend that actually contains humic acid to help prevent problems with the MG soil.
