Heeeelp! please

[Mindovermatter]

First of all soory for the pics they are from my mobile.
I have had major problems with these. They are bogglegums. The highest concentration of nutes I've had was 150ppm (250 total including tap water) so I dont think its overfert.

The first pic describes one with problem occuring in the beginning, they get dark/blackish spots in the middle of the older leaves.
The second pic show its progression to black colors.
In the third pic they get rust-colored and the whole leaf turn yellow.

not good at naming deficincies,

but im sure veryone is going to want to know the essentials:
light, size, ph of medium, that good stuff. .


wish i could help, can you get some better pics>?
good luck!


lots of Love and Light

what ph is your plant at and what nutrients have you been using and how old are they and what system are your plants in? just rockwool cubes?

 

[Mindovermatter]

Well they are in a bubbler. The ph drifts from 5-6.5. Lights are 125w enviro on 24/0. Temp of resorvoir is 65-70. Temp of chamber if around 75-80. Nutes are Hesi hydro grow (www.hesi.nl). They are 4 weeks old, about 3-4 inch tall, very stunted as you can see. Medium is one layer of rockwool, then coco in the bottom of 1L small pots, with bubbler reaching about 1/2 inch above the pots.

 

[Mindovermatter]

Ive checked your entire thread about sick plants stitch and cant say I can find anything that fits this

 

[MynameStitch]

how wet is the rockwool and coco?

did ytou wash the coco before using it?

well for one they need more food

which nutrient are you using there is lots of grow ones on that site

what is the NPK of yours?

what is your ppms in your res right now?

look ike phoshprus and nitrogen issues

you need to check your ph a few times a day when you add nutrients

and after they take it out dont use more to adjust ph, you need to get ph adjuster to fix it, some people use nutrients to adjust ph and then there is to much and burn there plants

use around 500 ppms if your water is RO
and use ph to adjust it

do not go any higher than 500 right now, you want to get them back up and growing then slowly up it when they start to grow

 

[Mindovermatter]

Here is the nutes:

I put the RW and the coco in a big res and stabilized ph for 24 hours with plain water and some root complex and enzymes before using.

They are very wet.

Every time I have added more nutes than 100 ppm they get these problems.

My ppm now is 150 (50 nutes)

 

[MynameStitch]

150 is nothing, they need more feed them get the ppms up to 500

and get rid of that nutrient, its completely out of balance and the info on there is outragous, EC 1.5? thats *!&@^!&(^@! crazy

just use enough to get it to 500

use 1/2 teaspoon per gallon of water for now..... how much water you got in your res?

you can use it for now but if you keep using it you wil have more nitrogen and cause nitrogen toxcicty, those are to high for cannabis

what other nutrients do you have available in your area?

another rpoblem is the b1 and other vitamins, its excellent for cannabis but they dont use alot of it and everytie you feed your givng them more and more, that nuttrient will cause alot of problems

thats like using superthrive with every feeding......

so please trust me get rid of that nutrient and find soething different..... i can help you find a new one just tell me which stuff you have acess too

 

[Mindovermatter]

but mr stitch every time Ive used more than 100 ppm nutes they get this way.
I live in europe so anything closeby here would be fine enuff.
the res is 3 gallons. I use GHE ph- but the ph drifts alot. I also add some enzymes as per direction. Someone told me it could be due to a lockout??

 

[MynameStitch]

get some other nutrients, but trust me your plants are lacking food and your ph needs to not go upand down you need to keep the ph around 5.5 to 6.3

the vitamins is whats causing the problem and the imblance of nutrients

i would get some nutrients first thing in the morning, do you have anything else besides that nutrient right now?

 

[Mindovermatter]

no
but I could get some canna aqua vega? is this good?

I know my plants are underferted...but I dont know what to do..since every time they get screwed as soon as I go above 100 ppm.

 

[Mindovermatter]

someone also suggested it may be due to my tap water, which is 100 ppm at 7.4 ph.
So was thinking of getting a particle filter.

Also...someone said the nutes were PERFECT for vegg..and you say the opposite..damn Im confused.

Should also add that the stems are purple/red colored if thats of any help.

 

[MynameStitch]

i havwe grown out bogglegum lots of times and i know the strain well

well whoever said those nutrients were perfect for veg should think again, those nutrients have vitamins with it, anyone who knows a bit about growing knows that using vitamins every watering causing buildup and the plants are not able to take in nutrients right

100 ppms tap water is fine thats not your problem

you can take my advice if you like or no, but ive been doing this for a long time and i know alot about them

your problem is your plants are hungry and your nutrient is wrong

any NPK for cannabis that goes over 20 mark is not good and is a complete waste

7.4 ph is near neutral all you need like i said before is get some better nutrients without vitamin b1 and others and get some phdown to control the ph without adding more nutrients to adjust ph


know my plants are underferted...but I dont know what to do..since every time they get screwed as soon as I go above 100 ppm

your plants are showing nitrogen issues

how much of that nutrient are you using right now? how many teaspoons per gallon of water?

and your rockwool should not be saturated, it should be moist and kept moist saturated roots cause lack of o2 and can cause nitrogen issues

its the size of the plant that matters, not the age

would you feed a steak to a baby?

and with your plants being stunted you dont want to throw a big increase in nutrients

500 ppms

i would use canna terra for now, but you need to be supplimeted with magniseum

filter for hydro is not mandatory, but i have seen plenty grow hydro with water like yours with no problem


you dont have a water softner do you?

its up to you if you wan tto take my advice, if you are not going to take my advice please let me know so i wont waste my time, i wont get mad, but i will get mad if you keep asking me questions and choose not to listen

cause its wasting my time
but ive been doing this for a long time now, i see problems and i have kkinda a gift for stuff like this..... i know whats wrong 98% of the time


your ph is also drifting because your plants are taking what little nutrients they have in the water which causes the ph to go up

 

[Mindovermatter]

Stitch,
OK I'll get canna nutes then.
I am not using any tsbpoons of nitrogen. I only use the 50ppm of nutes from what you saw above.
About my ph...Ive tested this many times: I take about 2 gallons in a large can (without any plants or nutes or anything)...put ph- down to 5 ph, put airpump in..8 h later is above 6...put more ph-...8h later its above 6...and so on..

 

[Mindovermatter]

Alright stitch I ordered some canna terra vega as you said.
Can you explain why they get the dark spots please?

 

[Mindovermatter]

OK I flushed the pots with distilled water as advised in another thread.
I am thinking about upping the nutes to 500 ppm.
But something tells me not to, since the 50 ppm nutes they have had yesterday is still on the same level, although the PH has increased to 6.5. If they had been hungry they would have eaten of the nutes and it would have decreased right? Or is it a symptom of lockout??

 

[Mindovermatter]

Ok so I flushed them..and afterwards some peep tell me I may have root rot in the RW...great

 

[MynameStitch]

i told you your medium is to satured, those dark purple spots are you talking about in the bottom righ picture you posted?

how big is your root system? roots that are not out of rockwool cubes that stay to satured causes lack of O2 and root rot issues and then stunting and the yellowing you are seeing

either way your plants ARE being starved, but because of what? there are several reasons

if your roots are not out of that rockwool cubes and your rockwool stays saturated, your plants may not recover now, some at least now that you flushed them

how many you got going? I would take one of the worst plants and cut open the side to see what color the roots are if it doesnt show past rock wool yet, then you would know if root rot occured, if not then my previous statement they are not getting enough food



those purple interveinal clorisis issues are phosphorus issues those dark purple spots

also distilled water, if you continmue to use this for your growing needs, you will need to get cal mag suppliment because distilled water has nothing, no minerals in it your plants dont get any nutrients from it, only to get them wet

 

[Mindovermatter]

stitch:

c'mon dont be like that, im a newbie and Ive panicked cause I got serious problems and everyone gives me different calls I dont know what to believe...
but I have done like you said and ordered new nutes cost me a hefty $30.
Alright I increase the nutes to 500 ppm now??
just give me a yes and I'll do it.

Roots: Some of the cubes got roots poking out..some dont..

 

[MynameStitch]

my bad i erased my post before you posted back, i thought you wasnt listening to me untill i seen there was 2 count on this thread, i didnt read your previous 2 posts before i posted my post


sorry about that, read up my post before your post above mine

as for the ppm's wait untill you know if you got root rot issues, because if you do its not going to work upping ppm's your wasting it and can cause more damage to the roots

you do need to know if you got root rot, plants this young that get hurt by saturated levels of water is very hard to recover cause there root system is delicate

older plants with bigger root systems recover easier depending on the severity
