What are my leaves telling me?

Hey there SwissKush , Im just back from your country lately, nice place , nice growers there :-) Anyway this looks like calcium / micro nutrient symptoms because of the rust spots on the leafs, the discoloration on the side of the leafs, and the fact that it affects the top growth not the bottom growth (mobile vs immobile nutrients) . What i see is that you're feeding 3 different kinds of micronutrients "diamond nectar" , mineral magic, and floramicro. so basically if you have symptoms but you're adding the juice that means you have lock out. I do really like diamond nectar, and i use it myself , and it's quite concentrated. On the other hand you're adding the other two as well. My best advice is to do a light flush water until run off then water 20% more of what you already watered. Then reduce the micro by selecting only one or two of them to make sure the lockout doesnt happen. Hope this helps ! 🚀
