@KushyLou, they're looking really frosty , congrats!! take care of how the leaves are curving up and getting sharp edges and burned tips ;
im not an expert, but from what I have experienced check the light your giving and the nutrient build up in the soil , maybe is to much and the plant can't take it , or also might be a molybdenum defficiency , or even roots problem , check this page I use everytime my leaves start to get different ;
