Spark my life

Your plants are very young. At this stage you won’t need to add any nutrients for a while. I would say you shouldn’t really worry about adding any until week 4 of the vegitative stage. Make sure that when you are feeding you start off with a 1/4 the recommended dosage that the bottle of nutrients tells you. Make sure to not over feed as this will cause more problems down the road. It’s a good rule of thumb that if you don’t see any dificiencies don’t worry about adding nutrients. Only when you start to notice deficiencies should you really start feeding. Good luck on your grow! Hope this helps!
