What are they,5-6ltr?Transplanting will effect them but I still believe they'll be much bigger than what they,ll be in those,id move them.Never use less than 11ltr for the final pot but never start seeds in big pots unless they're autos.Transplant in 3 stages with photoperiod plants.I cannot recommend seaweed/kelp enough.Its in all root booster all veg boosters and even some flower booster like canna boost.Its not a nutrient its an additive,stimulant.Its got at least 3 growth hormones in it like gibberelins and auxins.PGRs.The plant ones are fine but the man made ones are carsnigenic and banned in a number of countries.
