3 parts soil, 1 part perlite, Cup is plenty big for now, make sure it has drain holes in the bottom. What exactly does the soil contain?

No idea what's in the soil... I'll try and find out, but it's 2 weeks old... Wouldn't the roots be pretty developed by now?

The soil has no fertiliser added, it uses organic materials to help nourish the soil.
Answer me a few questions please.
Answer me a few questions please.
- Are you checking your pH before you water your plants?
- What is the temperature of your water just before feeding?
- Have you added any fertiliser to your water, if so what?
- What is your ambient humidity reading?
- How often are you feeding and how much?

I just checked what was in the soil, it said perlite, compost, forest materiel and wetting agent? Maybe I'm overwater? I water every 2-3 days, the cup usually feels light and the soil is dry.
I've been using tap water, I PH tested it with a PH test strip, and it was about... 5.5-6.8.
The temperature of the water is probably about the temperature in the grow room, which is maybe about 80-85.
No.
Don't know

Ok, next time you water make sure the soil is fully saturated. Pick up the pot and note the weight. Now the next time to water is when your pot feals roughly half the fully saturated weight.
Tap water has a lot of chlorine. Chlorine is deadly to plants. The amount of chlorine in tap water can not kill a plant but is not very healthy. Put some water aside to let the chlorine evaporate for a few hours.
Your pH range is quite broad slightly on the low side. For soil growing you need to keep your pH range between 6.3 and 7.5.
Your water temperature is way too warm. You need to keep it between 64F and 68F. Any higher and the water will struggle to hold onto any oxygen.
Also you need to keep a track on your humidty levels. This is vital for young plants. If your humidity drops too low then your plant will try to keep the air around the leafs moist. This will result in your root zone taking in more water and less nutrients. Which if you was feeding a chemical based fertiliser, you would quickly see a salt build up in your rhizophere. Giving you signals of overfertilisation.

Every time i water i do fully saturate it and get good run off. I just got more perlite, do you think transplanting it into a bigger container with much more perlite hurt it more then help it?

pH has a massive impact on the availabilty of nutrients to your plants. It can turn a good grow into a great grow. A lot of plant problems I have whitnessed have been down to incorrect pH. Just checking your nutrients pH levels can save you a lot of trouble and only takes a few seconds with a pH meter.
Your grow will only be as good as the weakest link in the chain.

5.5-6.8 is a pretty large range.
It looks like your lacking/locking out P, see the purpling around the edges of the leaves, thats a small indicator. I had a couple vegging plants that showed the same signs, and cured it with a phed flush and a nice feeding.
I would say you have over watering stress to boot. I tend NOT TO water till i get run off with seedlings. It can create a mud swamp at the bottom of the container, cause the roots are not developed enough to wick off the water.
No offense metal, but 7.5 is too high IMO. I feed soil 6.2-6.8.
not saying that I haven't seen people on the net grow great plants without PHing at all, but I ALWAYS do, and have great end results.

I wouldn't use that soil if I was you. There is definately some food in it as it says "active ingredients" and compost is mentioned. It doesn't have the appearance of soil I like to use, for instance it's all clumpy and off colored and the perlite is already a dark brown from absorbing moisture. I have never heard of this soil and when I looked it up it was from scott's who makes miracle grow products and the customer rating is 2/5 stars with almost 70 reviews, that's pretty poor. It really doesn't pay to get cheap or untested soil, I like my ocean forest personally. I use it right out of the bag but some like to add a bit of perlite to it.

Yes I know about ph issues thank you. Ph issues with soil grows are rare. soil mellows soil ph, alliviating extremes one way or the other. People here throw out ph as a common problem when it really isn't. But they keep throwing it out there anyway.
There is no such thing as a nutrient ph level...lol...you are confused with PPM...in fact I think you're just confused period.
