4th week flowering plant diing i think

this 1 4 foot by 4 foot plant Started browning and spotting 2 weeks into flowering. Started with black spots on middle leaves which turned to brownish yeloish spots with turned into yellow and brown dry curling up dead leaf. This ever since has been happening slowely making its way up and has killed many fan leaves and 1st and 2ndary growth. now the spotting is on the bud leaves.

The plant was growing very rapidly when the spotting started and continued growinf fast for about a week into th e diing of leaves, buds still seem to be growing fairly fast yet. but the leaves are still diing. I flushed a week and a half ago and just been using water lately. Because I was using max nutes before this happened I think it was nute burn but if anyone could give me a reason why its not it owuld be great because I thought it would stop drying out after I flushed it?>???

appreciate any input thanks.

You and all others should read this, it should answer all questions now and in the future, without pics- nothing else i can do...

Read more journals- see others struggles, and get some photos!

Cannabis Nutrient And Deficiency Table

To use the table just match up the plants symptoms with those on the table. Nutrients that are shaded Red are the problem. Find that nutrient in the text below the table for the remedy.

NITROGEN (N)
Pale plants, red stems, smaller growth. Rapid yellowing of lower leaves progressing up the plant. Add any chemical fertilizer containing N. Treated plants recover in about a week.

PHOSPHORUS (P)
Slow or stunted growth, red stems. Smaller leaves that are dark green. Lower leaves yellow and die. Add chemical fertilizer containing P. Affected leaves will not show recovery but new growth will apear normal.

POTASSIUM (K)
Affected plants are usually tallest and appear to be most vigorous. Necrotic spots form on lower leaves. Red stems. Leaves appear pale or yellow. Add chemical fertilizer containing K.

CALCIUM (Ca)
Lack of calcium in the soil results in the soil becoming too acid. This leads to Mg or Fe deficiency or very slow stunted growth. Treat by foliar feeding with one teaspoon of dolomatic lime per quart of water until condition improves.

SULFER (S)
Plants suffering from S definciencies exhibit yellowing of new growth. Mix one tablespoon of Epsom salts per gallon of water until condition improves.

MAGNESIUM (Mg)
Lower leaves yellow and may even turn white while veins remain dark green. Blades die and curl upward.

IRON (Fe)
Leaves on growing shoots turn pale and veins remain dark green. pH imbalances make iron insoluble. Foliar feed with chemical fertilizer containing Fe or rusty water.

MANGANESE (Mn)
Necrotic and yellow spots form on top leaves. Mn deficiency occurs when large amounts of Mg are present in the soil. Foliar feed with any chemical fertilizer containing Mn.

BORON (B)
Growing shoots turn grey or die. Growing shoots appear burnt. Treat with one teaspoon of Boric acid (sold as eyewash) per gallon of water.

MOLYBDENUM (Mb)
Yellowing of middle leaves. Foliar feed with chemical fertilizer containing Mb.

ZINC (Zn)
White areas form at leaf tips and between veins. Occurs in alkaline soils. Zn deficiency can be treated by burying galvanized nails in the soil. Chemical fertilizer containing Zn can also be used.

OVER FERTILIZATION
Causes leaf tips to appear yellow or burnt. To correct soil should be flushed with three gallons of water per one gallon of soil.

Ok sure my plant could be defficient with a lot of things, but don;t you think it would stop producing. Thats why I think nute burn the whole plant is drying up exept near the bottom midrange. Its like the leaves turned to yellow spotty brown black drying curling up. The leaves seem to stay attached and streched for sunlight with some green along the very start of the leaves.

What happens when you nute burn the crap out of a plant?

If anyone ever watched DBZ my plant looks like its been turning supersayan lol With the white hairs and yellow clawed upward leaves. it looks like it my not make it but yet the buds still look good but the crown of leaves around the buds are started to get the black spots too, The thc hairs seem to fall apart on affected spots.

I should probably mention. I started giving max flower nutes one week into flower, it says to give 2,5 -5 and I gave 5ml of 0 - 10 - 10 and 2.5 ml of 5-1-2 and 10 ml of 1 - 4 - 5

Now can you say over nute?

OK now I think I know what it is. Pottasium toxicicity mabey. Because its mutalating the plant.

If anyone know how to cure the problem or have any other ideas on what is causing c'mon c'mon

yes, and it sounds like you intended to do it! WTF were you thinking you when you doubled the recommended dose when they were still babies!!!

Keep that chart.... you will need it for your next grow. and best of luck with this one, your best bet is to start flushing, should have done that as soon as you saw the signs really...

your in pretty deep with this, and you may be ok, but damn- that was dumb hands down... do you feed your baby twice as much cause you want it be healthier...... i hope not

I will stay following to see if i can help anymore, but i am no pro grower....

Flush that shit...
OB

ps. I dont mean down the toliet, flush means double the soil capacity with water and force drain it, so that there are no more nutes in the soil... you should do it even if it wasnt burned out, because its very beneficial for the plant...

I actually did flush a week ago and have just been using water, but it is still happening but slower

thanks a lot for the input it said 2.5 - 5 so i was thinkin more like 2.5 for a small plant and 5 for a larger one. And the plant I got is pretty large. My bad.

Oh shit, just figured out my ph meter is broken, I have been adding 7.5ml of bumper ph down to 4 litres of water for 2 and a half months. I just checked my water with a different soil tester powder and it turned satan red, reder then 4.5 Then I added 1.25 to a different 4 litre and it turned orange at 5.5 H
HERES my question, clearly I mean thats pretty obviouse the ph is down, it all started with spotting. Maybe I should add some nutes???
Because I have already flushed once with 20 litres of water and watered with just water and ph down for the last 3 waterings. Do you think I should add nutes to my next water?

Get the PH straight for a week, then tamper with nutes, at low dose at first- half of RECOMMENDED- then do the recommended, then if your plant is taller than you are, consider double dose. But double dose is not good otherwise...

and you gotta let them settle for a second before you give them nutes, your 4th week of flower... 5 by now... prime time for hermy's due to stress- you dont want that!!!

Best of luck
GET PICS i am very curious lol

OB

Ill get a pic one of these days, lol "not down the toilet", funny.

Its like I can see every defficiency in the plant exept phosphorus.
