Plant not doing so well

[Dankgravy]

I got these clones and they had some cut leaves and burn marks when I got them, but these burn marks are new. Can anyone help me figure out what is causing this.

My first guess would be over watering. I have been watering once a day. I might start watering about every 35 or so hours.

I am using GH nutes.

Day 1 - Distilled water with 2.5ml of GH nutes.
Day 2 - Same
Day 3 - 1 gallon tap water with 1/5th cap full of GH Ph down. Flushed each plant with 1 gallon.
Day 4 and 5 - gave them tap water and ph down. Changed light to 18/6.
Day 6 - gave them tap water with some ph down and 1ml of each GH nute.
Day 7 - Same as 6.
Day 8 - Today Flushed with tap and ph down

Strain - Blackberry Kush

I water the hydro once a day

Roots were fully developed.



Two different plants in the pictures.

Any thoughts?

looks like nutrient burn ... what kinda light are they under? Sometimes if u can get them under an HPS (far away) they'll respond by growing out of it. But they got more than enough nutes built up in the roots for a few days. Just get them into a healthy environment, cool air, gentle light, no stress. Transplant them into a place where the roots can expand out, and start using those nutes. Plain water w/ a touch of cal mag...when u see a growth spurt, then u can start feeding again. Hope that helps

I dont think it really needs anymore nutes but I think Wiz is right just pot them in a cup of a decent soil mixture maybe with castings and perlite. just feed water atleast maybe for another 2 weeks or so. im not sure if im looking at the picture right but theres atleast 3 nodes on each clone? but yup I think they look too bad right now, im sure they'll be fine

Cool, thanks. Ya I will for sure higher the light a bit tomorrow.


Setup - I have an Ikea closet. One fan in the closet oscillating. I also have an inline fan on the side of the box. The light is a 400w hps. The doors are open a lot. They are closed maybe about 10 hours a day. The room is usually about 75 degrees.

I have the light 18/6

I see you have rw minicubes stuffed into big rw cubes....
Do you plan to grow these out in a hydroponics system ?
If not, then I suggest you get those little minicubes out of that big cube before the roots get fully grown out into the big cubes. You say you just got them, it is very likely they're not rooted into the big cubes yet and they can be transplanted, minicube and all straight into a soil or soilless medium where they would be much easier to manage being "hand watered" like you said you were doing. Its pretty simple to do by peeling away the big rockwool starting from the outside corners in small strips like peeling string cheese. Chances are, if those clones are newly rooted, that you'll get all the way to the minicube before you start seeing any root system. When you get to the point of seeing a good root mass...stop peeling and transplant it into the soil planter. You'll be glad you did IF you're just planning to hand water your girls.

But anyway... to your questions...
You say "GH nutes" and mentioned using some of "each" which leads me to believe that you're running gh flora multi-part nutes.

If that's the case, then the half teaspoon each in one gallon of distilled water you did on day 1 & 2 is wayyy too strong for new clones like you have.

Now day 3 you just gave them tap water with a willy nilly hit of pH down, flushing the big cub'age with a gallon.
Day 4 & 5 more tap water with more pH down.... arrrgh
Day 6 & 7 more tap water with pH down plus 1ml each gh flora per gallon
Day 8 (today) flushed them with more tap and pH down


Sheesh. First of all, buy a pH meter so you know what pH you're feeding them, you can't just willy nilly toss a capful of pH down into the water without having an idea why. A tds meter would be handy too so you can measure the strength of the solution.


Then follow a decent mix ratio plan for your gh flora series nutes.
I suggest either the Lucas mix, the h3ads mix or the 123 mix.

The 123 is a good beginners mix.

On the other hand...If you do transplant to a soil medium, there are much better newbie grower nute programs you can feed them with other than the chem hydro salts gh flora series route, which would be much easier to manage than having to do chem mixing...tastier too in the long run.
