guessing doesn't help, but since no one but the grower is at the grow it is difficult for anyone to know exactly what's going on. sodium light doesn't reveal anything except the gold glow of sodium light.
passive aggressive behavior is where a person creates conflict by avoiding an issue rather than dealing with it. I'm not doing that.
cannacat, earlier in this thread didn't you write that you've never used more than 3ml per liter but 35 ml per 10 liters is equal to 3.5 ml per liter. liveleap says that he has used a booster which I'm GUESSING is this:
http://www.cannagardening.com/cannaboost_a_real_boost
This page states that there is cal and mag in the fert. It also says there are many other nutrients. Liveleap seems to be following what this page is trying to tell us as 35 mls corresponds with what the company says to use: "In general, a 20 to 40 ml range gives the optimum results. A further increase in the dosage will flatten out the additional growth levels and very high doses might even harm the plant’s development. It will always be up to the individual grower to determine what dosage works best for their particular crop." In a post on the first page, liveleap wrote this: "i was up to 35ml/10l last watering with nutes and bottle says 50ml."
However, when reading over the early stuff in this thread, perhaps I'm wrong here, but it looked to me like liveleap was giving both other nutrients and the boost together. If this is the case, it could account for the dark green leaf color. It also needs to be remembered that liveleap is growing in soil, not coco. Many soils already have fert in them and adding more can cause trouble. Reading over the early posting, I saw liveleap mention growing in soil but didn't say exactly what kind, so..... liveleap, what soil are you using?
(This entire thread is a good example why it's important to put down details of a grow. You don't have to write a book, but the soil type, amount, temperatures, air flow, water, fert type and amounts and how often, are important details to put here to reduce the chance of people guessing at solutions rather than being able to pinpoint what's wrong).
