Coco. You are having magnesium deficiency. Coco has 2 draw backs it absorbs cal mag so it requires a supplement to grow in. 2 it has to always stay wet while keeping close track of run off ph. Vegging ph is 5.8. Flowering is 6.2 for optimum nutrition uptake for those stages. Anything above 6.3 or blow 5.7 will be lock out. Need any more assistance with coco feel free to dm me after selecting my answers. Good luck 🌱👍

So I watered (nutrition in the desc) and calmag 2 ml, because I thought it might be either lack of PK or cal mg. What else can I do? What about my watering schedule?

Yellowish color at the tips and wrinkles My plant has been yellowing for a day now, I think it is a deficiency of some nutrient but I don't know what it could be, I have thought about buying NPK. At the same time, there are also a couple of leaves that have slightly wrinkled the tip and have been half lowered.
