Lower light to 25% intensity. Better if you can download photone app and pay to unlock the LED. drop your ppfd to 150 until they recover.

ph down to 5.6 and it should not rise more that 0.2 in a 24 hr period if it does then let me know and we can correct that. Keep PH between 5.6-6.0.

EC 1.0-1.2

they should see noticeable signs of improvement with a few days. Then you can start to increase the light intensity a bit.

make sure you have decent air movement and shoot for around 60% humidity lights on.
are you using controllers for exh fans etc?

can you list your equipment and controllers

ok so, i will lower the light to 25%.

Just letting you know that bucket consists of 12 liters of deionized water along with:
4ml of ghe grow
5ml of ghe micro
5ml of ghe bloom
5ml of ghe fulvic
half a small spoon of atami bloombastic
2.5ml of Advanced nutrients calmag
After mixing said bucket, ph has at 5.8 so i didn't add any phdown.

Ph was at 5.8 last 13 hours ago(when i mixed the bucket), now it's at 6.4, i will adjust. (most of the time it rises exactly like that, and then i adjust to 5.2 or so, and it rises to 6.0 within hours and it stays there stable for more than 4 days, so im gonna do that again and hope i get the same results,unless you want me to do something else)

If i am to rise my EC, what nutrients would you like me to add? (i have all theese i mentioned, plus the whole 16 bottle advanced nutrients stuff, and i also have a Growth technology Formulex)

Now for the equipment:
lumatek 600w pro LED
one oscillating fan that blows directly at the middle of the plant in a very gentle and low speed (the tips of the leaves are barely moving in all parts of the plant and it is trained so the center of the plant recieves air aswell, so i dont think we have an issue there)

a cheap mist creating humidifier (its set in the lowest setting possible and this has the room at 55% during the day, but rises at 70, even 80% for small periods during night time, if i put a timer on it, it will stop during lights out and i imagine it will rise no more than 60%.. if you want me to set the range of humidity to be 50-65% at all times, i can do that using a timer easily)

i also have a dehumidifier, but i don't use it since my standard RH is upwards of 40 where i live (mediterranean climate)

as far as exhaust fans go i have one with a carbon filter on it, but i don't use it since noise is a huge problem for me (even the air pump is enclosed in a box with sound proofing cause even that volume of sound is bad for me) I keep an open window in the room at all times though, for some fresh air

For air pump i don't know exactly what kind of air pump it is, but i asked for a "more than enough" airpump at my local grow store, and got one with 4 ports and 2 of them are dedicated to said plant)

The room is small and easily controlled by a wall mounted AC unit i have, it also blows semi-directly into the tent and it has a thermostat, so i can set any temperature and enjoy it consistently with 0 problems.

as far as temperature goes the room is at 21-22 C at daytime and drops as much as 17.5 at night(rarely, most of the time it's at a stable 18 C)

water temps are stable are ranging between 20-22 C

i have no controllers, but i live where i grow and i don't go out much, almost never actually, so i can be 24/7 present and i can monitor and control things myself if needed.

i tried to be as analytical as possible to give you the best possible image of what's happening

You say the ec had been sitting at 1.4 ec for five days.

Did they drink much in those 5 days?

Click to expand...

The water was somewhat stable during the last 1 and a half week, it was lowering a tiny bit but im not sure if this happened due to natural evaporation, or happened due to plant drinking. i don't feel like they drank though

That ph swing is too large plants can handle a wide range of ph but do NOT like large ph swings.

do you have ph up?

i suggest a humidity controller… inkbirds are cheap and work well.


Use half dose of cal mag, grow micro and bloom only for now. Do not add the boombastic its a PK booster

i should mix up a new bucket? i used my last deionized water on this one, and it contains what i wrote to you in a total of 0.7 EC, do you think it's gonna make a difference changing the bucket again? or i can use that solution for the week since i am already down from 1.4 EC to 0.7?

(cause if i do, it will be with 0.2 EC tap water instead of 0.0 deionized)

Well with the DI water you have no real ph buffer so that may cause some ph stability issues. But imo you should be at 1.2 EC as Gh usually will settle at about 5.8 ph providing you use enough. So you can try to mix equal parts of GH to reach 1.2 and then ph to about 5.6 and see what the drift is over 24 hrs. If its 5.6-5,8 then your good

if this is the only issue then im gonna stick with deionized water for some days (for knowledge reasons to see how it behaves etc) and my next feed will be 1 EC with equal nutrients.if you think that the current mix will cause trouble i will be more than happy to change it again... but what about pk boosters and all the other nutes? im gonna run just the ghe trio till the end in equal parts? will it be enough?

i will do what you suggest though, can you provide any good source for me to start understanding the relationship between fertilizer and ph?

how can i be sure? my water temps are very good,i have enough water oxygenation and i also use beneficial bacteria...i dont see what else i can do to combat this, if i even have it

Add a lil peroxide to your water it will clean up everything quick and won't hurt your plant in any way

Equal parts ti the end is fine. Your grow so do what ya like. Only giving advice on ideals.

the light was the main issue but i do see other things things as mentioned that will likely caise you further issues

my guy you are a gold mine! thank you for everything, and thank you for bearing with me through all my problems lately,i promise to help other newbies in this forum aswell as soon as i know what im doing. i am not here only to recieve. its the least i can do for such valuable advice!

One last line of questions : how long do you think running the light at 25% will be required, will i be able to have it working at 50% at any point of flowering, or should i finish with just 25%? will that hurt yield? is there a window say during the last 2 weeks that i should up it to 50%?

Thank you so much, i will be posting progress in less than a week, so you can see how they responded, i will make the reservoir you described made of equal parts and observe the differences that it make with the ph, and hopefully learn from it!
i wish one day i can repay the favor! stay strong my dude

It all depends on plant responses and how much your able to correct. Your light will likely never need run more than 75% and can dtart to slowly increase once you see nee healthy growth

Thank you a ton! thank god i get to solve theese problems before the flowering stretch , this way i have a shot at producing ok bud, and it's thanks to you, thank you again. will be posting whatever progress occurs within the next few days

Yeah keep us up to date and we can give you the small tweaks as needed

Do not give your plant water with no nutrients… EVER. your light is too much back it way off. That is your problem 100%

"Do not give your plant water with no nutrients… EVER"

That is something ive not heard before. Can you elaborate

not in hydro. Plants NEED some ions. I have never heard of anyone doing this in hydro… in soil sure because the soil will add to the water nutrients and ions. Without a minimum level of nutrients a plant cannot perform vital functions and will deteriorate very quickly.

Im just curious where you found this recommendation for hydro? I have never seen it anywhere.

already looking better! leaves are starting to widen and the tips of the leaves are starting to become straight and pointy, will post pics tommorow or after tommorow

Here she is! Already looking better, she's at 6.0 pH, so far the EC hasn't moved, still 0.8! Big difference for sure, any tweaks you recommend?

Alright will do, then post pics again in like 3 days? should i use ghe grow/micro/bloom in equal parts? and if so, should i do 1.2 ec till harvest ? general info about how should i think during flowering?

nutrients availiable to use :
ghe silicone dust (i dont use because it doesn't dissolve)
ghe grow
ghe micro
ghe bloom
ghe fulvic
atami bloombastic
Advanced nutrients calmag
Formulex from growth technology
the whole 16 bottle advanced nutrients line
