Hey DS, athos you're correct your plants need something, in fact what they need is micronutrients. There are three categories of plant juice: nutrients , that's coco a and coco b, then there's additives that's rhiz and zym for you... then there's micronutrients, something super important for your plants! so micronutrients are minerals commonly found in soil but that you need to add to your coco grow : they are calcium and magnesium most importantly but also silicum, mobidglium, iron, and others... so you do need to add cal/mag to your feed. problem is cal/mag uptake is through the roots is not that efficient. So what i suggest you do is make a foliar spray with 2ml of rhiz and 2/3 ml of cal/mag and spray them until wet once a day for 3/4 days. the rhiz stimulates the growth hormone in the plant and the cal mag is absorbed at a very high rate of efficiency through the leaves. they should recover within five days like that. hope this helps ! π
