Yellowing of the bottom leaves is normal, some times leaves get “nutrient splash” due to when watering some get on leaves. Now if it’s the middle of the plant different. Your nutrients and soil are good as temp. plants need a 18/6 light cycle , they need sleep to NO; 24 hr light !!!, as found out one needs to treat clones a it different
