As coco holds no nutrients you need to give them on every watering. Get a EC/PPM meter and you can use this as a general guide. Week 1. 0,6 EC (focus on calcium / magnesium additive) Week 2 1.0 EC continue with cal/mag and add grow nutrient. Continue with this until end of vegm if you are going to veg a long time, you might want to go up to 1.4 EC. Flower. start just like the previous weeks and after the 2nd week go up to 1.8 focusing on bloom nutes.

Hey Steven, if you've noticed that the stem of your plant has turned purple, there are no more indications of issues. There are certain marijuana strains that automatically grow with purple stems, more so when the seedlings are budding, or even once the plants start receiving cooler temperatures during the night. If your plant seems to be in good condition aside from the stems being purple, refrain from making any changes for a one or two weeks. Provided that your leaves appear to be healthy and there aren’t any of issues you are aware of, most likely the purple stems are nothing to be concerned about.

Is it straight coco? If it is it doesn’t add any nutrients you have to add those yourself
