And second week from germination done ! I should've thouhgt about that, I have to get her 4 more liters of coco fast, don't want her to feel restrained because of the pot. Also ther's a little mark on one leaf and some feel a bit quirky. Do someone can help me with that ? Hope it's not that bad. Plus, as I'm using Royal Mix, I don't want to start feeding too early, my Plagron schedule recommends me to use vita-race and power roots during growing but for the moment I only give clear water because I don't want nutrients burns from the beginning, should i wait like 3rd or 4th week ? Letting her grow a bit more and then feed her or wait until flowering starts ?
