First Timer Indoors

These three are just getting enormous. I'm having Some problem with over crowding and the only real serious defo has been on the aberration (Pot 3) so far, started to add the flowering nutrients as the will be put into flower by the 30th hopefully. By the way I think pot 1 has been showing some deficiencies most likely calcium. anyway only three leaves lets hope the new nutrient solution will help on that.
