Looks like you have alittle Magnesium and Phosphorus deficiency. nothing to worry about now but may cause problem in the long run, have you started fert?
My opinion the soil looks really wet and my battles over the last 2 weeks with over watering and poor soil drainage have caused about everything possible except death to my plants. I would def watch the watering and check for proper drainage.
Don't introduce any nutes. Your soil is full of them already! I would suggest letting your soil dry out so your roots can breathe and you will see these "deficiencies" disappear. When you do start to feed in a month or so (or whenever your plants starts to show that it needs nitrogen) I would suggest going the route of an active aerated compost tea. Take advantage of the fact that you have some time to learn about teas before your plant actually needs any. Your soil is alive with microbial activity! Learn to feed your microbes..they in turn feed your plants. It's a natural cycle and the best thing about it is that you cannot burn your plant with a proper organic tea but you CAN overwater. Let your plant tell you when it is thirsty. The leaves will droop suddenly, you will think that you have lost your plant but thirty minutes after you give water them they will stand right back up as if it never happened. This will give you a sense of how long your plant can go before it NEEDS water. After you get a sense of how far your plants can go before needing water then you can water next time before your plants get to the point of drooping. Also go to the biobizz website and read about your soil. Happy growing
