New Plants One seems to Be Sick :(

[gardenfather]

Im having problems with one of my Plants From what I was reading maybe its my ph? Im not too sure as im new to growing.

Also I just today put the timer to 12/12 unless you think its to early and they are to short?
1 plant i did LST the other i just let grow normal. The sick one is the normal one.

but as you see the sick pant has yellowing leaves, brown spots.

What medium and nutrients are you using? And do you check the pH? The pH being off can cause many nutrient deficiencies.

Looks kind of like calcium deficiency to me? What is your PH do you know?

Ill have to check my PH soil level today,
I usually ph balance the water to 6.5-6.8

Medium is soil.

Nutrients are nuti+ it also auto-adjusts the ph level of the water.

I will definitely test the soil with my soil testing kit today to see what the ph of the soil is.

Also do you think I sould start 12/12/ today or keep the 18-6 still and let it grow taller?

I don't know your setup, but depending on strain they can go from 1.5-2x size once they hit flower. So you want to try to fill the tent up, but not so packed you are blocking light from reaching bud spots. It looks like you got a scrog net setup which I have no experience with unfortunately so I cannot offer anything specific.

I appreciate your reply

Promix is peat based and more acidic than normal soil.....looks like as said above , your medium is too acidic and causing lockouts and imbalances to begin.....Did you add lime to your medium before you planted to buffer your medium ?....As far as when to flip bro.....X can be anything if the plants have never been run before , and again as stated above stretch can be great or little to none strain dependent , so the only way to know is flip and see where they end up.....

Looks like you`ve got some cleaning out underneath to allow proper light penetration as well as air flow , so good luck and....

Peace....DHF..... …….

I never did anything to the soil. just added the seed and thats it. Is there a way to fix the soil? should i bring down the ph lower? I mean ill guess when i see where the ph of the soil is I will be able to tell. but if its to high, is there a way to lower it? do i just ph it lower for a bit?

Thanks once i test my soil ill post the results.

Not familiar with that particular packaging of promix but I use promix hp and since it is actually a soiless mix I try pH my nutrients from 5.6 - 6.0. Right now I am using MaxiBloom.

What DHF and others said is correct. It looks like pH imbalance. Check the pH of your runoff. It's probably low (acidic) and needs to have some lime added.

I didn`t wanna stress him out any further by telling him Promix is actually a "soiless" mix with additives like mycos…..anyways.....

Do you buffer your Promix with dolomite lime 190 ?....I mean.....is Promix like coco and not necessary to add lime as a buffer ?.....and ….if anything the medium is most likely too acidic and not alkaline and the ph will most likely need raising , not lowering.....anyways.....

Good luck.....DHF..... …….

 

[gardenfather]

I just added the soil. used this promix (Wont use it next time ill go to coco or a better soil)

I just took samples of my soil and tested its Showing

Potash = low
Phosphorus = verylow/low
Nitrogen = low
PH = 7.0

Heres a photo of the test in case my eyes are off.

Heres a url to the test I use

Just goes to show that X can be anything without knowing where EC and PH reside from the get as well as all during the grow......so feed the plants and up the EC.....Set your ph lower than before so it won`t get back toward neutral as fast..... PH needs to swing from lower to higher so all macros and micros can be uptaken…..anyways.....

Now you know howta stay on top of things so.....Good luck and.....

I do not.....but I do a drench/flush with 1/4 strength roots and then let it dry before I transplant into it.
