Jeez first grow and you guys are telling him to give up and go dirt .... wow! It is a sorry looking grow but its the first and it lived, thats got to be a good thing!! So first off dont touch them, don't trim, and don't cut, being new and strain being an auto just let them grow. Go light in the nutes and perhaps change res more often, i run a 130 litres and change every 7 days and more near the end. Dont spray them after they developed buds IMO due to higher risk of moulds, in veg i have found spraying to be a good thing though.
