Leaves starting to taco and wilt!

It was going so well…last night I waterd this girl, after waiting days for the soil to dry out a little. And, I added a timy amount of ff veg and bloom. Like 1/8 tsp each.
I am using a three way meter and ph measures exactly 7. As does my water, which is well water, so may be suspect.
I am reluctant to do anything because its in pre-flower, and I dont want to mess her up?
She a bubblegum auto, and is the tallest of the four plants I have.
The other three plants look fine. The room is a bit warm, but I have trouble believing these plants are that picky!

Your ph is too high. For soil 6.5 is great all the way up to 6.8.


I second what @Laurap
Said pH your water and nutes down a bit your plant sounds like is is locked out


What is a bit warm? And how is ventilation?

Pictures, pictures pictures. They say a million words! Also a support ticket always helps :smirk:

COPY/PASTE the below list into your forum post.
Answer these simple questions the best you can.
If you do not know, or do not use something; Just say so = NA

Strain; Type, Bag seed, or NA

Soil in pots, Hydroponic, or Coco?

System type?

PH of runoff or solution in reservoir?

What is strength of nutrient mix? EC, or TDS

Indoor or Outdoor

Light system, size?

Temps; Day, Night

Humidity; Day, Night

Ventilation system; Yes, No, Size

AC, Humidifier, De-humidifier,

Co2; Yes, No

If you can, upload a picture of your plant. It helps the diagnosis, if needed.

Add anything else you feel would help us give you a most informed answer. Feel free to elaborate, but short, to the point questions and facts will help us help you :sweat_smile:




I hope the picture came through. Third try.
Is there a household item I can use to lower ph?
Lemon juice? Vinegar?
I have a fan in the window right in front of the plants.
The room is about 80 at worst. Im in the South!
If I run the A/c in the room it flips off the breaker. The two bloomspect lights take all the juice.
But I could run a heavy duty cord into the next room for the lights.
The other plants look fine right now. They are in an earlier preflower.
Thanks all.

These 3 way meters are NOTORIOUSLY inaccurate FYI. (Unless you spend a boat load of money on one)

You really need a good, dedicated digital PH meter that you can calibrate. 6.3 to 6.8 is your range. This is the single most important thing you will ever buy for your grow.


This is the one I use, as do many others here. That, and some PH up and PH down and 7.0 PH Standard Reference Solution and you are good to go.

While you are at it you can pick up an inexpensive TDS meter and measure your well water to see how hard or soft it is. The meter will be useful for feeding.

You can lower PH with lemon juice, vinegar, citric acid etc or use the product designed for it. The advantage of using a commercial product is the phosphoric acid in PH down is beneficial to the plants. PH up can be done with Baking Soda but there are cautions about long term use.

Also: PH just before you water. After any and all nutes are added. Do not PH liquid ahead of time as the PH will drift towards it’s original value within 12 hours.


Is your meter one of those probes that stick in the dirt as @Myfriendis410 is suggesting
If so follow his direction and get yourself a meter like the one he posted
And I use vinegar but have also use pH up and pH down made by general hydroponics
Or use vinegar to bring your pH down or if needed use baking soda to bring it up

Yes it is one of those with two probes.

Right now I can do some lemon water ( I have a tree!) but for future I can order the product and the better meter.

I am concerned about the additional watering now, having just watered last night.

Maybe I will repot with some fresh soil…is that going to upset the grow cycle?

Agree strongly with @Myfriendis410 , the pH is all important for getting good results. I also have the Apera ph20 and it is fantastic. I have only calibrated it once in 18 months. I re-calibrated it once just to make sure it was right and it was spot on !

On the pH Up and pH Down is very useful as you are never sure of the pH of the lemon juice and using baking soda causes problems with your plants. It forms a salt in the roots and is very hard to flush out. It raises all kinds of problems with the plants not being able to absorb the nutrients. In the long run, it is much cheaper to buy the reagents and know what you are getting. I used baking soda on one grow and it took a week of flushing to get the pH to stay the same in the run-off. NOT worth it to use a substitute for the real reagents.

Always pH test your water AFTER adding any nutrients and use it fairly soon (several hours). Do not let it sit overnight then use it without re-checking the pH.

Good luck on your grow. Develop good habits and your grows will become the thing of dreams after a while. Jerry :us: :man_farmer:


I think you are locked in now but file it away for the next grow.

When you go for soil look for organic if you prefer but get something that has NO timed release, NO moisture conserving; just good clean potting soil. I use FF but it may not be available to you in your area. Home Depot sells a soil called “Black Magic” and is a Scott’s organic product re packaged for mj. It works but is kind of over priced IMO.

Ok, so now…do I treat the others- proactively- they show no signs of problems.

Ditch it
How have you been measuring your pH going in?

Yea they are a bit far along for repotting
Lemon is fine but getting a good meter to measure your pH going in will be a good move
Next grow I would get the meter
If you wanna get some pH up pH down thats fine but lemon juice or vinegar to bring it down works and baking soda to bring it up

Mine looked about the same and the PH was to high. But I’m a beginner could be anything lol

I figured I had nothing to lose, so I did the following:
repotted into a soft pot, with the intent of checking for root rot. I’m in a very humid area.
Tried lemon juice, ph didnt change.
Now I know the ph meter I have is definitely bad.
Then I gave her a little fox farm big bloom in a good dose of water.
I also moved my lighting with more light directly over the top.
She looks much better today!
Still have hope!

Do not repot your auto. Be patient, let it dry out again, then flush with properly pH’d water.
