    Looks like your pH is off if you're growing in Coco.

    You need to keep your pH between 5.8 and 6.3 at the absolute max. 5.8 is the spot you're supposed to be at. So you're just experiencing deficiencies caused by too high of pH.

    Once your plants are a week or so old or have three sets of regular leaves you should water the entire pot so you get 10 to 15% runoff and do that every single time you water. You also want to have feed every single time you water.

    It can drift up over time, but there's no substitute for a decent pen. I have a very cheap one that I use as a backup only but it cost at least 80 to 100 bucks to get a decent one.

    Ph rises over time. A decent “cheapish” is essentials they’re about 40quid i think for ph pen.
