White/brown spots and curling on leaves

Hi Guys,

I need your help to identify and solve a problema I’m having with one of my plants. It’s still on the early stages.

Some white/brown spots are showing up on fan leaves, some sides and tips are curling. I already treated it with some pesticide and fungicide, and am watering it with tap water that is left 2 days outside to remove chloride and ph adjusted to 6.2-6.4

Some pictures below. All help appreciated!

This would be helpful to the pros and they’re gonna ask for it.

Also, when did you calibrate your ph meter last?

Thanks for your answer.

I don’t have a ph meter, I use an indicator to measure the water.

Following is the information for the ticket

Strain; Lion’s Haze Feminized from power seeds

Soil in pots, Hydroponic, or Coco? Soil in Pots

System type? NA

PH of runoff or solution in reservoir? Ph of watering watr 6.2-6.4

What is strength of nutrient mix? EC, or TDS: NA

Indoor or Outdoor: Outdoor

Thank you!

This is good, sounds like you have a plan.

But what comes out the bottom of the pot is just as important as what goes in when we are talking about measurements. Think you could get a PH reading of your run off?

It would be beneficial to you to gather up some of your run off water that comes out the bottom of the pot, and measure its PH, it won’t necessarily be the same as what you put in the top.

@Tincho, when you take the sample for runoff, sample the last 10% or so.

OK Guys, so finally I managed to measure the run-off water, and got a ph < 6.2! (can know th exact value because the color scale ends there) I suspected my feeding water might be too acid, bu I measured it and got the values I expected, 6.2-6.4. Is this possible? Seems weird that the soil is acidifying the water…

Also, I noticed some small flies on the plant, they are not white, more dark-black. And the plant seems to be getting worse, and now some of my other plants are starting to show the same symptoms.

Got some pictures taken just today.

All help is really apreciated!20171110_18515820171110_18520520171110_185209
