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?
The soil has no fertiliser added, it uses organic materials to help nourish the soil.
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?
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.

- Are you checking your pH before you water your plants?
It's the ph police everybody run ahhhhhhhhhhhhhhh
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.
