What's the problem???

What's up guys,

Check the pics below....not sure exactly what the problem is.

These three plants are about a month old. I tried messing around with LST and that's why they're shape is all jacked up.

My soil is on the airier side...some MG potting soil mixed with a lot of perlite and black cinders. This yellowing got bad about a week ago.

First plant seems to be the worst. As you can see, not only the lower older leaves look bad, the new growth seems to be affected as well.

I don't know....you guys are the experts. I don't really care about these plants as I was just messing around--but I am concerned as I have a few autos just sprouting and I don't want the same thing to happen to them.

I have a few ideas, but I'd rather keep my mouth shut so I can get your unbiased opinions...

THANKS!

to me it looks like an Mg def or a severe N def/nute burn

what are black cinders? that soil doesn't look right to me looks like you burned her.

black cinders are pretty common in the hawaiian islands...used a lot for landscaping, etc....good for drainage.

not sure of exactly what is made up of...

Black cinders are lava rocks.

They should not be used for any application where you are planting. They are used primarily in landscaping

I would assume you are using black cinders in place of perlite. Not a good idea

Your plants are definitely suffering from nute burn, that is obvious.

Advice: "stop using black cinders"
