Doing my first ever grow. Most of the plants are looking like the pictures below. After doing some digging could this be possible iron deficency?

Resembles a PH issue. Is that a DWC set up? When running a reservoir the nutrient mixture will have PH drift and checking and adjusting daily helps with this

Thats a automatic watering system actually a cool way to water my brother runs the same one. @jtanner53 what medium are you growing in. Welcome to the community!

An iron deficiency looks like this:

Ty for the welcome, I am using floraflex’s medium which is in the link below.
I am using the ph controller in the link below and the ph usually reads between 6.0-6.4

Gotcha, Coco range of 5.8-6.0 would be ideal. Nice set up Growmie

• What strain, Seed bank, or bag seed
Half the pots are Apple Fritter and the Other half is Girl Scout cookies
• Method: Soil w/salt, Organic soil, Hydroponics, Aquaponics, KNF
I am using floraflex’s grow medium and nutriests as well. I am going by there recommended dosage which is on there website.
• Vessels: Pots, Grow beds, Buckets, Troths
All the plants are in floraflex’s pro-pot. Which are just 5 gallon buckets.
• PH of Water, Solution, runoff (if Applicable)
I use a ph controller and the ph reads about 6.0 to 6.4
• Indoor or Outdoor
Indoor
• Light system
I use a uMol reader for the lights and leave it about 1000 uMols
• Temps; Day, Night
85F
• Humidity; Day, Night
74-80%. My humidity is constantly fluctuating since right when the mini split turns on my humidity drops by about 20%. THis was actually a problem since at first I was using ink birds humidity reader and it was very accurate but it took minutes for the true reading to occur. So by the time it hit the right humidity level it was actually much higher. At one point I saw the humidity level at 95%. I switched humidity readers to AC infinity and the readers happen much faster.
• Ventilation system; Yes, No, Size
No
• AC, Humidifier, De-humidifier,
Mini Split with Humidifer, really no need for a dehumidifer here in Los Angeles.
• Co2; Yes, No
Yes keep it about 1100 ppm
If growing Hydro some additional questions:
-DWC? RDWC? Autopots? Ebb and Flow? Other?
-Autopots
-Temperature of reservoir
I have a aquatic heater in there and keep the water at 79
-TDS of nutrient solution
Not sure
-Amount of air to solution
I have 4 air stones in the tank

I will keep a closer eye on the ph, and thank you. Literally first grow ever trying to figure out the kinks. Once I saw the plants like this kinda got my worried.

You need more light for extra CO2 to make any difference. 1200+ PPFD. Anything less and CO2 is a waste of time and money. CO2 demands a closed environment, higher grow space temps, and high nutrient levels. CO2 requires highly technical grow methods that hobby growers have a hard time maintaining.
Temps too high invite problems with water quality and root health. What is the temp without the heater? Do you have a chiller available? Hydro temps should be ~70F. You don’t mention PPM, which is also very important and may be problematic.
The sweet spot for hydro is a pH of 5.8. Correct your reservoir temp and pH and you should be good. Everything else looks okay, though I would like to know what nutrient PPM you are maintaining.

It’s a big learning curve Growmie, good pointers from @MidwestGuy
I turned everything on for the reservoir this includes the heater, ph controller, 4 air stones, and 2 circulation fans.
I lowered the water heater temp to 71, ph was reading 6.3 and I set the controller to 5.8 now. In terms of PPM I am getting very inconsistent readings. Above the air stone bubbles I would get 900 ppm and off to the side with no bubbles I would get 500-600

Sounds like you are going the right direction.
Happy growing.
