or thats good no if you have no deff then dont worrie less is always more. watch for stage growth to increase feed. i.e say veg. once they have rooted and taken you will see the plant start to develop so up it a bit. then middle veg it gets it volume and width up it then ect ect. or up the feed till you get the slightest tip burn i mean the slightest i wouldn't really call it burn. but you see the tip go whiteish color thin the feed its max for the plant. every time you feed write don what happend with that amount and watch the leafs you ill soon have it dialed in perfect as long as you have a good base line thats not burning go up 0.2 to 0.5 mill at a time and you will be safe i promise
