Just gave them 2 cups of waterNo u just fed one litre that right if so wait 3 days n take pics n I'll look a good way to tell is if the top layer look dry pook ure finger in upto the first knuckle and if it's still bone dry water and try to get used to the weight of your pots when fed n when dry.
Yeah just keep them under the 400 all the way through veg they'll still growing huge if done correctly and use the 600 in bloom since hps I'll let u know when to switch also use the 400 in bloom but have the lights directly side by side for both spectrum and higher light par peace ✌
