My First Grow

@Medes, The required fertilizer also depends on your soil. Is it prefertilized? If yes you have to subtract the amount. For example: My soil was prefertilized for 2 Weeks, the dosages (5g/L) on the package are for 6 weeks of "vegetative growth". Therefore I can only take the amount required for 4 weeks which are only 2/3 (since we only fertilizer with it a 2/3 of the 6 weeks). I did it twice because I vegged so long. Far to long in hindsight. Lets say you also use lightly fertilized soil. For 11L you should take 3-5g/L * 11L = 33-55g for 6 weeks veg. We have to subtract the 2 weeks of prefertilized soil: 0,8 * 33-55g is what you need in that case. You shouldn't use bloom fertilizer in veg since it has less Nitrogen. NPK should be more N than PK in veg. The bloom fertilizer is more PK heavy than grow. I heard that you can also just use humus if u don't want to buy a Nitrogen rich fertilizer. It's organic too.
