Can't Figure IT OUT!!

[Hogg]

I have had this problem also. It started in 4th week veg and continued. I am now at 8 weeks flower so I will get some buds but it looks like one of my plants may die before I harvest Friday. I tried all kiknds of things first I flushed then I bought Cal-Mag. I never did get it corrected. Not sure the problem I know for sure it was'nt over-feeding or over watering and the Cal-Mag didnt really help.
My last thought is that I have a Ionic Breeze located in the ajoining room going on all the time and maybe my issue was that, are you using any ionizers for odor control?

you can buy pure calcium and magnesium powders...... but it is best if you don't know exactly how to use it, if you get stuff premixed and concentrated specifically for botanical use ........ I sent you a pm about using it with the Fox Farms..... that is the question I have..... at what rate have you used the slow release powders?[/QUOTE] Well, I also use all fox farms soil, nutes and micros, what is the big secret about using the cal-mag bonticare concetrate? I used it, at what ratio, Should I have

I just bought the Cal/Mag plus by botanicare i hope this shit works.

 

[rivers2gates]

it is not mag. i have the exact same problem right now. mag def is shown BETWEEN the veins along with praying leaves pointing straight up. what we have is coming straight from the veins themselves. turn the leaf over and you will see that the veins are dying first. it is something else.... i am stumped

If I have to say Nitrogen in this thread one more time I may well....
The calmag plus has N init doesn't it?
Feed me Seymore!

 

[420Ben]

yes it does have nitrogen in it 2.0%, damn this morning my flowers look even worse. I think they might be dying.

lower leaves only? Leaves that have been damaged will not be "repaired" by the plant, but replace, get em all off and continue on

 

[420Ben]

i pruned off the lower leaves yesterday and today i noticed top leaves are messed up and dried up. Its targeting mostly the fan leaves.

 

[420Ben]

ill post some pics in a little bit

 

[theloadeddragon]

you sure you didn't over water?

 

[420Ben]

By over watering do you mean if the soil was still moist and watered it again?

 

[rivers2gates]

the leaves are not drooping. isnt this a sure sign of over watering?

 

[theloadeddragon]

not necessarily..... its one of the signs though.... the crisping of the leaves could be though as well..... severe over watering..... and yes watering while the pot is still "heavy" and "moist"

 

[rivers2gates]

ITS NUTE BURN or PH. I flushed for three days They were getting worse with every flush, now all new growth is coming in green with no burnt tips. too bad i figured it out this late. keep flushing and go to home depot and buy some super thrive they will come back. TRUST ME ben.

 

[420Ben]

Well the pots were light when i watered them. I do have some super thrive, im going to wait until the soil is dry again before i do any flushing.

 

[nellyatcha]

i am having trouble figuring out what is going on with my plant. slowly all the leaves are starting to look nasty with brown spots on them. help me please !!
also eventually the leaf will turn completely yellow with the brown spots on them.

rep me for this its buron def. and add some nitrogen as well bro

1rst of all Boron almost never occurs in indoor grows. Just so you know boron effects the top part of the plant first, in Ben and My case our lower fan leaves where the first to be effected. NOT BORON

OK here are my recent pics of the plants. I took them out from my tent so i can get better pics.

Jorge's is the tallest one.

Much better pics Ben now we can really see what's going on.
Classic Phosphorus deficiency mate get some potash into them or whatever you got that's high in 'P'.
This is quite common in flowering plants.
It can look a little like nute burn but notice the brown doesn't start at the tips as nute burn does but along the center of the leaves.
Then they twist, dry and curl.

Edit: and get some nitrogen into them too.
