If it's only on the old growth don't worry about it once a leaf changes color it can't change back and in my opinion all that is is not enough nitrogen one of the times u watered it even tho ur last dose was fine doesn't mean 3days from now it is every strain likes different amounts the guides on the bottles ect are only average guidlines. But that's something that u master with each strain. So dnt worry about it the plants are looking amazing so far keep up what ever ur doin there beautiful and the perfect shade of green
there perfectly healthy
