Sonic_Ystarted grow question 3 months ago

Hi. I'm a beginner and this is my first grow on coco coir. 2 of my plants having problems. I'm watering about every 2 days with half amount of nutrients, that the nutrient company is showing on their chart. So i'm not sure, if it's too much nutrients or not enough nutrients.

Magnesium deficiency. When you grow in coco coir, you need to add cal/mag at least weekly if not more often.

It could be stress from topping more then anything. To check if you have a salt build up in the soil, next watering/feeding make sure you get 20-30% of the volume you put through the plant in runoff and check the pH of the runoff to make sure your coco is at the correct ph.
