3x3x6 tent
DWC maxibloom & maxigro
TSW2000 Mars Hydro

Looked fine when i transplanted her 2 days ago into her new bucket with nutrients & did some high stress training to try to canopy

I used (per gallon) 1 teaspoon maxigro in distilled water with 2 ml of cal mag and 2 drops of physan20 to control root rot

PPM was at 1130
PH has been fluctuating but keeping her at around 6
TEMP is 80 degrees

Getting yellow leaves almost overnight
Any help or advice would be appreciated.

I don’t do DWC and I’m sure someone else with more experience then I will chime in. But to me she looks either nute burnt or light burnt, how is the water consumption is she drinking heavily? 1,100 could be to much if she’s a heavy drinker or high intensity light is causing the heavy drinking?

light is an LED about 16 inches from top
i always thought 1100 would be high but there have been problems in this setup and i dont know why - so i read about LUCAS formula using 7 grams of maxibloom - which is about 1.5 teaspoons - i thought that was too high - so i only used 1 teaspoon of maxibloom

she was drinking a lot & looking pretty good up until this recent change. She had not been receiving cal mag or the drips of physan until this change. I was thinkig maybe the physan poisoned her (even at 2 drips per gallon) so i have refreshed her water and nutrients, still added 1 ml of cal-mag too. I am hoping this resolves the issue

Hmmm possibly a lockout on phosphorus.. to much cal/mag can cause P. lockout
Or needs more nitrogen..

I am afraid of losing her (like i have others), is there a process i can do to save her & maybe isolate the issue? I have problems diagnosing issues, sometimes i wonder if its root rot cuz the roots will be beige and other times i wonder if its locked out. Kinda makes me think about going to soil next time lol

I would pull the lights back a bit, the way the leaves are pointing down looks like it’s trying to get out of the light, if it’s not light burn and is nute burn less light = less demand for food.
it could be a lockout due to cal toxicity, calcium moves together with almost every element in a plants structure.

the light is as high as she goes but i am going to dim it down to about 75% of power. If it's lockout i guess i should just let it sit in tap water for a day or 2?

I would let someone else respond about a res change but I wouldn’t do plain water. I would probably do 600-800. Or see how the lighting effects them. Did you recently turn it up?

Mag can block hormones in the plant prevent phosphate to do its thing..
Try a new nutrient solution with out as much cal/mag.. you could try a lighter nute solution but i doubt thats the problom..
I would run 1300 ppm using the gh flora serise in my set up

she recently went from a less powerful light to a more powerful one - although she was sitting much closer to the other light

forgive my ignorance but isnt GH Maxibloom essentially the same as the GH series?
but i HAVE been thinking about switching to Advanced Nutrients.

The flora serise is a bit different..
The maxi is dry nutes right?
Try the flora trio liquid nutes.. if you do just dont use the grow to much.. the flora serise tends to have to much nitrogen ..

It’s hard to say, that’s the thing with cannabis. Some people I’ve seen run 1,400-1,500 ppm while another guys says he can’t go past 700. When it comes to cannabis there is only best practices, no laws. Every strain is different and even every pheno. What works for you might not work for me, what works for me might kill yours. No two environments are alike.

thats a whole other issue for me is PPM
my first grow - i didn't check PPMs or PH - and grew a monster - it was awesome.

Since then i've been paying attention to PPMs and PH and having major issues.

I often wonder how well the PPM meter is actually reading.
I've been using 1 teaspoon of dry GH maxi gro for veg and 1 of dry GH maxibloom for flower - in distilled water. I am paranoid about root rot so this time i added a couple eye drops of physan20 and some cal-mag. On top of that - it's moved to a different tent with a different light and i did some high stress training. So like the title says - there is a lot going on.

At the same time - Whenever i resolve issues, i do so many things that it becomes impossible for me to figure out what FIXED it

As long as you do regular res changes and have ample oxygen (air stones/ disks) in the res/roots zone you shouldn't have to worry to much about root rot..

that's just it - i am doing this for a friend who lives 2 hours away - res changes are maybe once a month. it has a 6" airstone in a 5 gallon bucket. That's why i am about to have them switch to soil - they don't seem to want to mess with it often and i think soil will end a lot of issues

If thats the case.. then sure, they should go to soil.. or promix drain to waste..
