Your plant(s) will be fine. The pic you showed seems to be a nitrogen deficiency, which is not unusual for cloned plants, as the plant/cutting didn't have access to nutrients (it began to use up it's stored nutrients, hence the yellowing of the leave). But now that you've transplanted into the FF soil, those roots will expand and they'll start getting those nutrients and bounce back strong. Just relax and give em a week or so.
As for PH, you want dolomite lime (not hydrated lime), preferably powder but pelleted form will do, and mix about two tablespoons/gallon of soil before transplanting. This will create the proper PH range for your plants to absorb nutrients. I assume you've not done that, which is not a big problem as FF soil does contain *some* ingredients to balance the PH. Just go to walmart and get a PH test kit they sell for fish tanks (they're relatively cheap). Measure the PH of your tap water and adjust if needed (buy some PH up and maybe PH down too) before watering. A range between 6-7 and you'll be fine, as plants will be able to absorb all the nutes they need.
Are you feeding on top of the FF soil, or just watering? And are you checking the Ph of the water you're using?
