on the label there's written 2-5ml with 1litre o water.i'll start giving them gradually the ammount of fertilizer suggested. when they will be transplantedinto bigger pots and then into the ground the ammount of water i'll guve them will increase like 4 litres of water every plant, this means i have to give them more fertilizer??

yeah that is pretty much what it means, like i use 1/2tsp of nutes because it ask for 1/2tsp per gallon, i have 4 gallons but i want to use 1/4th of nutes for right now so i just use 1/2tsp for all of my 4 gallons for right now

hope this helps
