My plant is yellowing please help!!!!

I need help with my plant!!
I noticed a bit of discoloration 3 days ago.
I just transplanted my plant into a 1 gal.
The soil is 40% OF, 40% HF and 20% perlite. I use reverse osmosis water ph’d between 6.0-6.8, .5 ml liquid seaweed per gal, and 1 tbsp of molasses per gal.
My temperatures are high usually 70-85 and humidity is all over the place cause my humidifier runs out but is usually between 50-70

Both of the soils you're using have food in them. Enough to feed that small plant for a few weeks. Also in good soil there is no need to PH as it will buffer jtself. Just good watering habits and getting your grow space environment under control is all ya need.

I was using 80% HF and 20% perlite but yesterday the yellowing got a little worse and so I did some research and thought it could be a nitrogen deficiency. I also gathered some information somewhere that OF is high in nitrogen so I was going to use this soil before going into flowering but decided to use it yesterday and transplanted. When I check the ph it’s at 8.0 so should I still not ph it? I can’t control my temperature right now because air conditioning is out . I try to check on my plant everyday but I sometimes am busy so I have to check on it every 2-3 days

I also am using a 600W MarsHydro Led 28” In away

OF is a hot soil. I never had good luck putting small plants in it. I used OF for decades and I never phd my soil. I use straight happy frog for my seedlings and clones with no issues. I usually start feeding at quarter strength after 3 weeks in happy frog. When I transplant into OF i don't add any food for almost a mknth. So that soil has everything it needs to keep your plants going food wise. If I were you I'd focus on environment more than anything. I use several water sources for my different grows, city,well,etc OF and Hp both buffer just fine with no adjusting.

Do you see any fungus gnats or any bugs?

Did you ever grow tomatoes outside or anything like that?

I wouldn't worry about one yellow leaf. It would be nice to have a focused pic.

I'd be more concerned that I was watering correctly (looks pretty dry for just transplanting). Keep temp under 80 (all the time), humidity between 50 & 70 is pretty high and you're feeding it what? Liquid seaweed and molasses?

I asked about tomatoes, the nutes tomatoes need are very similar.

Did you ever hear of anyone feeding tomatoes seaweed and molasses? How old is that seedling?

I personally have only grown tomatoes in hydroponics, not soil.I watered today. I can’t control the temperature because my air conditioning is out, but I can control the humidity because I have a humidifier. What should the humidity be around? Yes only liquid seaweed and molasses. No I haven’t, but I have heard from many professional growers that have great results with both

I think you're going to need a more balanced diet going forward. Molasses doesn't actually feed a plant.

Humidity over 40 can make a fertile environment for mold later. People grow weed in Arizona at 10.

If you have a 600 watt light and only one plant, put it in a bigger pot.

Why are you growing in soil if you've grown hydro tomatoes? If you have the stuff and experience? What did you feed your tomatoes, just out of curiosity?

Balanced diet as in? I just transplanted my plant from a solo cup into a 1 gal yesterday. The plants blew up right after but blue dream became slightly more discolored. I’m only 3 weeks and 3 days from germination. I have 2 plants. Blue dream and blueberry OG. Blueberry OG is doing perfect and looking very healthy. This blue dream seed grew abnormally from germination. I helped a friend grow tomatoes not my setup. No nutrients we ran aquaponics

Looks ok to me, bit of yellowing after transplant is normal, roots need to find water, fill new pot, it's a misconception that soilless mix(what your using) is ready to be used straight from the bag, you can obviously but really you should pre activate it first, this means you just water it a couple of days before you transplant, this gives the bacteria enough time to grow a bit. But it's a nightmare transplanting into wet soil ,especially in a sog /scrog. Always water from the stem if you transplanted dry or around the edge if transplanted wet. Always ph imo, 6.5 , 6 is too low,bag ph fluctuates greatly, your in soilless not soil, there is a difference
