Athosanswered grow question 6 years ago Autos need as much nutrients as regular plants. Guess feeding is a sure way to have trouble. Those spots your plant have are most likely early nute burn. For now stop feeding, let the plant feed itself from the soil, you have weeks before you have to feed anything, at least a month if not more. And get a pH meter and EC / PPM meter they will help a lot in feeding without burning the plants.
