Thought i had it under control.....I THOUGHT IT WAS BAD PH.......But now im not sure

[ValleGrown]

basically describe your garden
soil (medium)
nutes
lights
temps
humidity
feeding & watering routine
ph & ec (if you know em)

the more you tell us the easier it is to figure out

no problem

my cab is 22*21.5*46'' tall.
using some nutes from local garden shop. 8/50/24 i thnk.
last feeding was about 600ppm without the tap water ppm. tap is at 312ppm? Maybe CHLORINE??? JUST POPPED IN MY HEAD.
light is a 250hps horticulture bulb.
temps have been fucking awesome man. ranging from 64 at night to highest peak temp was 90 i think but that was before i stablized. they are now about 75-85 at the most.
Rh is pretty good man 31-40%
Feeding and watering i normally feed every other watering. flush every couple weeks.
I ph my water with GH PH KIT so i give em what looks like 7. Run off how ever was terrible. flushed 4 gallons of 7ph water and the runoff kept coming off as around 5. then i ph'd with some water above 7. the deeper teal dye that comes out. prob about 8 or 9. the ph came out a little over 6 i'd say.
EC...NO CLUE MAN>

built my cab 2x2x4 so if that makes more sense

u got root rot dont u on that big plant thats budding and thos 3 new pics of the babys they need tranplanted see how the leaves are startin to sag

no no no no the three new pics are the same plant. just a few week ago. you really think its root rot huh???

[ValleGrown]

the sagging leaves were due to a watering/feeding i think. so thats where im coming from on this whole root rot thing. i think you are over exaggerating this problem. the plant below was in a party cup. it sprouted on the 17th of sept last year. she had some heat stress. and had to perform surgery. she survived however hermed on my. i grew her out anyway in the same type of pot. she showed signs of this late late late in flowering like the last couple days. so i am opposed to this root rot thing...kinda... i just need more of a conviction. you know?

Thank you... LOL you crack me up bricktop lol (we are not worthy..... we are worms!!!) lol

 

[riddleme]

no problem

my cab is 22*21.5*46'' tall.
using some nutes from local garden shop. 8/50/24 i thnk.
last feeding was about 600ppm without the tap water ppm. tap is at 312ppm? Maybe CHLORINE??? JUST POPPED IN MY HEAD.
light is a 250hps horticulture bulb.
temps have been fucking awesome man. ranging from 64 at night to highest peak temp was 90 i think but that was before i stablized. they are now about 75-85 at the most.
Rh is pretty good man 31-40%

EC...NO CLUE MAN>

You forgot soil (medium)

several things that bloom nute is way high in P which is serious overkill for container gardening

your tap water is potential problem, however very few places still use Chlorine, most now use Chloromine only 2 ways to get rid of it, I run my water thru a brita filter, removes chloromine drops the ph a whole point (in my case)

your PH is way off you should be flushing with a ph of 6 at least (I do 5.8 and putting in a high ph'd water getting a lower ph runoff means the medium is out of whack, possible salt build up but could be the soil itself, what soil and how did you amend it?

everything else looks fine

 

[ValleGrown]

the plant is like about 25-28 inches id say. im using hard water. so im told 300ppm i my feeding is about 500-600 of actual nutes. so that puts the ppm at about 800-900
i switched to bloom nutes about a week or two after the first hair popped out...
no pests. no pruning. i pinched the top about 5 or so days ago. that could be why its a little thin up there. ..... but other than that i thnk i answered most of those. just with pics. not words

 

[Brick Top]

u got root rot dont u on that big plant thats budding and thos 3 new pics of the babys they need tranplanted see how the leaves are startin to sag

Do you mean root-bound when you say root rot? If you actually mean root rot then it will take a whole lot more than just transplanting into larger containers to help.

i am using mg moisture control with a personal blend of perlite. just to where it looks even you know...?
i used that same bloom nute on this plant with no problems. but im not ruling that out. every plant is different.

[ValleGrown]

how would i know if its a salt build up

 

[Brick Top]

i found this out by reading and i have read 4 every foot of plant the plant need 2 feet of roots so growing a 3 ft plant in a 5 gallon bucket just dont work i grow 2 foot plants in 4 ft trash cans and my leafe dieing and yellowing leaves stoped

A 5-gallon container is large enough to grow a 3 foot tall plant .. and you do not need 4 foot trash cans to grow 2 foot plants. I always preach larger pot sizes but you have gone way overboard on size and what you think plants need.

I don't know what you read but plants will try to maintain as close as possible a 50/50 above soil and below soil area of mass, amount of plant matter, so while roots are in a very different form than what is seen above the soil, stem, branches, leaves, buds, a healthy plant will have very close to the same amount of plant mass below the surface of the soil.

Here are a couple pictures, one of a root-ball and one of a pot with roots coming out the drain holes, both are examples of root-rot.

and mine have neither

 

[ValleGrown]

maybe root bound.....but i know its not root rot

 

[riddleme]

how would i know if its a salt build up

salt build up lowers the ph

 

[ValleGrown]

salt build up lowers the ph

i see. so could that be the problem... what do you thnk Bricktop? whats your prognosis

 

[riddleme]

i am using mg moisture control with a personal blend of perlite. just to where it looks even you know...?
i used that same bloom nute on this plant with no problems. but im not ruling that out. every plant is different.

MG with moisture control one of the worst soils for MJ, I'm not a MG hater but anything with moisture control is a bad thing

the 3 things I have mentioned is your most likely cause

 

[ValleGrown]

Blame the girlfriend on the mg moisture control bro... Lol i was sick and she went to go pick up the soil lol...had gnat larva in it to.. But killed those little fuckers ahahahhahahahha!!!! (evil laugh)

 

[Brick Top]

maybe root bound.....but i know its not root rot

A root-bound plant can experience many different problems but necrosis between the veins of leaves is not one of them.

A Potassium deficiency can cause necrosis (dead/dying areas between leaf veins) on the older/lower fan leaves.

In soil Potassium gets locked out of soil growing at ph levels of 4.0-5.5. Potassium is absorbed best in soil at a ph level of 6.0-9.5. (But I wouldn’t recommend having a ph of over 7.0 in soil) anything out of the ranges listed will contribute to a Potassium deficiency.

But your pictures don't really look like it is a Potassium problem. I would expect to have seen more damage around the leaf tips and edges.

Maybe I missed it somewhere but where on the plant(s) did it first show up? Lower large fan leaves? If so did it then spread or keep to the lower large fan leaves or did it show up at all levels of the plant more or less at the same time?

 

[ValleGrown]

so nute lock out due to the ph being wayway acidic. below 4
