Yellow leaves please advise

Hi folks. I’m trying to figure why the yellow leaf on this little fellow
My first guess is overwatering so now it’s 3 days without any water. Should I give it another day or so without watering and see how it goes? Thank you!!
I’ll add a few pictures

@Rickyy welcome to the forum. Can you answer as many of these as poss to helpnus help you?

What strain: AK triple haze

Method: Organic soil

Vessels: Fabric pot

PH of Water, Solution, runoff (if Applicable) N/A

PPM/TDS or EC of nutrient solution if applicable: N/A

Indoor

Light system: LED 2 x 100W (2 x 600W like) 20/4 hours

Temps: Day 25, Night 24

Humidity: Day 40%, Night 40%

Ventilation system — Yes, Size N/A

AC, Humidifier, De-humidifier, Co2; — No

What kind of organic soil? A ph meter and tds meter will be very helpful is determining how much nutrients are in your soil. Is this a photo or auto? I would water until 20%runoff with water that has been sitting for 24 hours to help woth chlorine evap. I would get your humidity up as high as i could along with temps close to 80 if poss. Ph could be an issue as well, causing lockout.

Welcome to the community , Is this a cannabis friendly soil? Most cannabis friendly soil you would not need to feed for at least 4 weeks. My first thoughts plant looks hungry.

Soil is organic multipurpose compost, not sure how cannabis friendly is. The water is filtered tap water.
Never did a ph test for either water or soil.

Today I’ve diluted some dry feed (couple of grams) in a few ounces of water, and sprayed a bit at its root, just enough to penetrate and reach the roots.

I also did spray some water on the tent’s walls and the humidity is now at 41%. The temperature is 81.
Turned of one of the 2 lights, to bring it down the temperature a bit. Or it’s ok, and I should keep both lights on?

I’m new at this, this being my second attempt on growing. The first time I failed. I grew an Euforia that reached nearly 6 foot without any sign of flowering after 14 weeks.
I’m still trying to learn more, and hope I’ll manage this time.

Thanks a lot for your help buddies!

@Rickyy g’day there are some great reads like the grow bible book or download from ilgm on this site to learn stuff aswell as asking here on the forum too, and ppl that have used led lighting an soil should be able to help some more. :slight_smile: gd luck mate happy growing.
