Anyone grown og lemon kush before...Im bit worried because although they look quite fat, they are a touch yellow...whatever i feed them doesnt make much difference

When plants show deficiency symptoms on lower leaves, those symptoms never go away, even when you satisfy their nutrient needs. If the yellowing stops progressing, you've taken care of the problem.

Don't go overboard upping the nutrients, or your next post will be about nitrogen toxicity symptoms.
