HELP! Plant dying from middle up!

[anarchy2465]

hi i have 3 plants all the same age in the same soil and with the same pH. they have all been fine until just recently each plant showed yellowing in the middle of the plant with the tips and eventually the whole life dying. after a few days it started spreading up the stalk with the pistils turning brown and dying. why is this happening?

more info:
pH: 7.0
regularly fed nutrients

Any chance of showing us a picture of a MJ plant and not a bush from your garden?

 

[natorious]

There's a forum only for non mj plants.

 

[smokybear]

I thought that plant looks kind of strange for a mj plant... Take care and be safe.

I know you are just doing your job but believe me that is what I tried first. Hosting from another website is a last resort. I uploaded them to marijuanapassion.com first and the thread didn't display the pictures so I had to embed them.

To the rest of you, this is a MJ plant. I wouldn't come to a marijuana forum only to ask questions about a plant that isn't a cannabis variety. That would be kinda dumb...

Did you uploaded the correct picture, this sure doesnt look like a MJ plant.

Miracle grow is no good for MJ, it has all the essential micro elements missing.

I use Bio Bizz bloom for plants in flower, google it.

Your PH needs to be 6.5, this is very important.

How many hours of daylight do the plants get?

I am sure this is MJ. That is the right picture I just took it an hour ago. How can I lower my pH? And why is it so important? My plants have been growing fine up to this point. Also why does the brand of fertilizer matter?

Oh yeah and the plants get 15-16 hours of sunlight. I'm located on the West Coast

 

[HippyInEngland]

If you say its a MJ plant, then thats good enough for me

MJ is a specialist weed, it needs simple yet important elements, these can only be absorbed in correct doses if the PH is at 6.5

The chart below will show you why it is important and which elements are impossible for the plant to absorb if the PH is out.

Manganese and Iron are locked out at high PH.

Brand names of MJ feed doesnt matter, but MJ needs specialist food to grow optimally.

Looks like some kinda mutant to me.

 

[leafminer]

Guys, it looks quite similar to my 'Secret Agent" which as most of u know, I am breeding to be as unlike MJ as possible. The leaves have a few side-serrations but the later leaves not. OK now to business:
1 tablespoon to about 1.5 gallons of water spread between 4 plants
NOOOOO! A tablespoon! That's a massive amount! You are killing your plant with MG. I bet the soil has been buffering it until now and you've reached th point where you have a toxic load of salts.
FLUSH it.

what amount of fertilizer should i be using? and by MG do you mean magnesium? because i actually haven't been giving them magnesium...

 

[zipflip]

and by MG do you mean magnesium

miracle gro

huh? can you elaborate a little please?

sorry i was asking you to elaborate on how it was killing my plant? are you saying miraclegro is killing it, or overfertilization is?
