young plant turning yellow

[riseup]

Hi, she is on day 15 and yesterday I noticed that the lower leaves were starting to turn yellow, starting from the tips.

The pot is 4" in height, 5" diameter. Im using an organic pre-made mix. It was supposed to have nutrients in it, what do you think is the problem ?

I have placed an order for biobizz nutes, but they will get here in a week or so.

Well and I just noticed that the dude that posted a thread below me has the exact same problem.

lack of light, lack of nitrogen, and overwatering is my guess.

I don't think that it is a lack of light, I have about 180watts of cfls running pretty close to the top.

It could be overwatering though, I'll see what I can do about that. Thanks.

Whoa, I must be having a major N def then. Plus overwatering.
My plant is topped too, by the way.

make sure your soil drains properly, and only water when it's dry....keep the lights right on the top of them and have a oscilating fan blowing fresh air on them at all times...and you'll get really fast vigorous growth!

Soil does not look fluffy. Perlite is your friend. Looks like you need ferts. Adjust the fert water after mixing to ph 6 using an acid or base. Things to use are in my signature "how to make your own ph up and down".

Okay, thanks for your advice.
When I think about it, I have been watering my plant too often.
