Hi there. Try and vary ph between 5.8 and 6.3 for coco. I don't use your brand of nutrients but I do grow autoflowers. You are probably running a high Ec. With autos you tend to find they don't like to strong a solution. EC about 1.2 to 1.4 is usually where they like it, some a little more some a little less. Invest in a Ec pen and check your levels.

hey there Skyhi, you have a calmag deficiency . you can tell from the yellowing on the edges and the rust colored spots on the leafs . That's because you have a heavy light schedule and the plant needs more calmag to regulate photosynthesis but it cannot absorb enough nutrients. you can try upping your calmag (bioheaven, i think) or try using your calmag in a spray twice a week to try to treat the symptoms and to treat the root cause you would do well to reduce your light schedule as much as you're comfortable . If you're not using calmag, you'll definitely need to start using it. Hope this helps ! 🚀
