Hey, on my biggest plant, the leaves are starting to turn yellow from the outside and getting brown spots. Is that a sign of over-fertilization? All the other plants don't have this. Or is it too little?
It looks to me like a mixture of calmag and nitrogen defiancany I would make sure you are following your feeding table correctly for the week you are on. Feeding tables are great for growers as the company have done the hard work for you and already tested thier products to get optimum growth rate :) nice looking plant anyway doing very well for your first grow buddy mine was an awful train wreck haha best of luck for a nice harvest buddy :) keep up the great work.
