my plant needs help!!!

[justlovingit420]

hey dude i wouldnt trip unless the whole plant is doin it leaves will tend to change colors but what you want to pay attention to is the top of the plant what you can do since ur using miracle grow is to water with a dish washing liquid which will clean the tips of the roots in case of salt build up i did and never had a problem check my plants out have a good day and remember dont try everything that everyone suggests because what i can see on hear is theres alot of amatuer growers here that dont know what theyre talkin about when it comes to growin advice later

Whoa. Back easy there.

From Stinky Attic the Chemist:

Dish soap, or any type of soap for that matter, is useless for 'cleaning' salts off your roots.
It is good for dirty dishes.

Salts can sometimes, depending upon their solubility, be dissolved in a SHITLOAD of water. Otherwise you need a chelating agent. It comes from the Greek for 'claw' and is a chemical that grabs ions and makes them less reactive, thus unable to combine into their insoluble salt form and fall out of solution into your dirt. Sample chelating agents are Oxalic acid or EDTA.

If you have salt buildup, there are chelating products on the market that are safe to add to your plant water. And some fertilizer companies are smart and make ferts with the chelated form of whatever it is.

Chelated Iron is a really common one, because as the oxide, it falls out of solution as iron oxide, or rust.

Dish soap has no place in your watering scheme. It is not good for the soil- you need certain bacteria and fungi that live on and around the roots, which, if not present, organic material in the soil is far less available to the plants and you might as well just stick them in a pot of hydroton.

OMG you just got me going on a rant. I hate it when newbs with a post count of like 4 come on here and start spewing that there's so much misinformation and THEIR way is PROFESSIONAL.....

Fuckin A.

ok u guys now of the leaves have it and its starting on the upper to middle growth, none on the new, im thinking its ph, but one of the leaves went completely yellow and now its crumbling, the next one up is going yellow with little brown spots, i need help bad

[easymack]

i ment other leaves have it**

[stinkyattic]

It looks like either a nute burn or a severe magnesium deficiency. You could get either from feeding with only MG. Flush that plant and give it cannabis-specific fertilizer with micronutrients. FoxFarm grow big etc.

Okay.
I already told you what's wrong with your plant.
Did you flush it?
Are you still using that shit miracle kill-your-pot?
Fix those things and if the problem doesn't go away, then, I'm baffled.

This is what it is.
You over fed them.
And the Nitrogen builds up in the fan leaves (starting at the top)
And burns.
It could be from the wrong ph in your water.
It should be 6-7.

It looks like Mag dificency because when you over dose MJ on Nitrogen it locks out the Mag.

Flush it a couple times.
Alot.Flush it real good.
And raise the light a few inches.
Watchfor hermies.
You can hermie them from over feeding.
It takes a good 7 days for the nute burn to totally show up.
So in a few days it will look way worse.
And then start to heal.
Watch those nute levels.
MGrow sucks for MJ.
Get some Black Gold or Foxfarm.
