thnx for the tips, by the way the leafs are streaching up, is this a sign of some definecy, or it's because of underwatering ? but I watered them with a cup of water 12 hours ago, so this shouldn't be a problem. oh yeah, I've got some fert, it's N-P-K 3-1.2-2.4 how often should I fert with it ? and what strenght solution ?
