HELP! Don't know what I'm doing wrong

This is my first grow. I’m in the blooming phase - Granddaddy Purple. My leaves are wilting and some on the bottom of plants are turning a litttle yellow. I’ve had fungus gnats and treated them with DE and Jack’s Deadbug. I don’t think I’m overwatering because I don’t water till the soil is dry when I stick my finger in 1-2 inches. I’m concerned that I’m going to lose my plants after making it this far. Here are a couple of pics.

A couple of suggestions:

Wait until the day after you seem to think it is dry. Wet/dry cycles are extremely important for root health. That said, drooping is common and normal if it corrects itself within 4 to 6 hours. Some plants can be twitchy, especially if it is an auto. If waiting a bit doesn’t help, then try watering a little more. Drooping is very common around watering time. Experiment a bit and you should be able to minimize it.

It’s normal and you shouldn’t worry about it.

You aren’t going to lose your plant. It is fairly healthy.

Dark green leaves mean the plant is getting too much nitrogen. I would skip a feeding or 2.

Do you know your runoff pH and PPM? Let’s get some more info so that we have everything nailed down:

What strain, Seed bank, or bag seed - I’m growing Granddaddy Purple autoflower that I got from I❤️GM.

• Method: Soil w/salt, Organic soil, Hydroponics, Aquaponics, KNF - I’m growing in Roots Organics soil.

Soil brand and type

• Vessels: Pots, Grow beds, Buckets, Troths - I’m growing in a 5 gallon black container w/drainage holes in the bottom.

• Runoff pH - I have never watered them to the point of having runoff.

• Runoff PPM/TDS or EC

• Indoor or Runoff.- Growing indoors.

• Light system and wattage - Using an LED panel. Not sure of wattage, but it’s a 350R I got from HLG.

• Temps; Day, Night - Haven’t checked temperature, but I’m growing indoors in a bathroom. I keep my AC on 72 and have a fan in the bathroom to circulate air.

• Humidity; Day, Night - Have not checked humidity.

• Ventilation system; Yes, No, Size - No vent system.

• AC, Humidifier, De-humidifier, - AC set on 72 as stated above.

• Co2; Yes, No - I don’t know anything about this.

If growing Hydro some additional questions:

-DWC? RDWC? Autopots? Ebb and Flow? Other? - I don’t know what any of this means.
-Distance of liquid below net pot (DWC) - I don’t know what this means.
-Temperature of reservoir - I don’t know what this means.
-TDS of nutrient solution - I don’t know what this means.
-Amount of air to solution - I don’t know what this means.

Everything looks reasonable except that you are not monitoring and managing root zone pH and PPM. These are necessary for controlling the environment. Overfeeding and underfeeding both have potentially serious consequences, as does an improper pH, which can cause nutrient absorption problems. Suggest getting pH and PPM meters and managing pH to a range of 6.3 to 6.8 and managing PPM to ~1,000. Blue Lab and Apera both make quality meters that are used by experienced growers. I use an Apera PC60 meter which measures both pH and PPM.

Overfeeding usually results in a low PH. You cannot manage it until you understand it.


Thank you. Do you have any information available that I can read to learn more about it?

Yikes! I just looked at these meters. They are expensive. What should I be paying to get what I need?

I get it. The way I look at it is as a business case. Properly managing these factors can make the difference between harvesting 2 ounces of weed or 3/4 of a pound of weed per plant. You do the math.


Thank you for your help. :pray:

Hey jaz, @MidwestGuy has you covered 100% if your gonna grow it’s not worth the effort to not make a decent effort which means spending a bit of $. The rewards will cover the cost. Look into the apera ph20, good meter without a big expense


Thank you. I appreciate the recommendation


your btter off spending a little more. i bought a cheap ph and tds pen. and they shit out. FAST! now i have the apera 20 ph and tds meter. just over a hundred for both (together) i would hav spent less if i didnt buy twice. also if your using synthetic nutes, you should water to run off, about ten to 20 percent. it helps get those old salts out.
my plants have made a 180 since i started doing these things


I am using Roots Organics nutrients. Did you get your meters at Amazon? Do you by any chance have a link? What does “tds” stand for?

Thanks. :v:

Total dissolved solids. It’s the baseline for measuring what’s in your water, like what’s in it naturally and whatever you add to it


You don’t really need the fancy pants one, I think there’s a less expensive option for about $50
