Yellow leaf edges

There is some spotting on the leaves in the 2nd pic. background ones have a lot. It looks a lot like calcium issues but that should not be a thing if you feeding them CaMg? I'm not seeing a lot of NPK labels on most of their products and some of the stuff you're using looks to be part of their living soil lineup and others part of their plant health series. It might need a different approach. The Ca issues is weird. do you agitate the container to mix it all up before measuring? I think the stuff you have been feeding it is to much and is building up in the soil. Its a liquid feed, end of day and a bit of runoff helps prevent lockouts and buildup. The leaves are looking extra Rich so guessing its getting a good amount of N. Its also smart to feed once then water when working with soil to prevent runoff requirements. Also all their stuff seems to be acidic when looking at their SDS, PH of 3.5 and 4 for products. The feed chat on the profile of the nutrient says you should be using the while lineup. but it does not give a real breakdown on nutrients in things https://bucket.growdiaries.com/static/nutrient_item_photos/1430/2032-6788-cleankelp.gif Best to find out what your feeding them in terms of NPK and then also in its EC/PPM values as that will help you determine if its to much. You should be able to email them and ask why the products are without NPK labeling standards and what it registers as, if they beat around the bush about it might be from poor quality control as batches are not coming up the same or they don't want to invest money into testing the product. and to me both are red flags. Over all weird compay,
