let the soil dry out before you water again,also be careful with temp if you turn the heat in room up to 80 it could be much higher where light is at.if you can put a thermometer near the plants but not directly under the light and keep temps in the 70s. do not water until soil becomes somewhat dry each time. and in soil if you use organic amendments you do not have to water until it runs out the bottom but just gets damp all the way through nor do you have to worry about burning the plant.best of luck.got to be hard if someone just droppes a bomb on you with no info if he is a grower ask him what up.
