Week 1 was uneventful. In the first few feedings of every grow, I get this very brown runoff. This goes on for the first few weeks, actually. Always wondered what caused this. There's this alleged "cation exchange" in the first few weeks of the grow due to the heavy calcium in the fertigation solution necessary when growing in coco. If you don't go calcium-heavy early, your plants will go calcium deficient early, which is a nightmare. This is why starting fertigation early is essential in coco - you should be fertigating with calcium heavy solution about 24 hours after what I call "Day 1" - the 1st moment when you see the cotyledons are open and squarely looking up at the lamp. So on "Day 2" you should start fertigating. Why? Because coco has no inherent nutrients, and in addition, will just eat the calcium right out of your solution. So a little seedling planted in coco coir in a puddle of only water is just sitting there being eaten alive by the coco, basically. The coco only TAKES at this stage. It GIVES nothing to the plant. So you gotta start fighting this problem right away by supplying all the nutrients to the coco coir plus EXTRA calcium. (BTW, I start on Day 2 with about 0.4 EC and end the week close to 1.0 EC). You are trying to create an artificial soil for the plant. Get going with it. This is how coco growing ends up being like quasi-hydro or manual-hydro growing. So I always wondered if the cation exchange caused that brown water or if it's just micro-dust getting dissolved away - or both. Week 2 is when the fun begins - LST begins.
